Colors That Start With Y: Beautiful Names & Codes
Colors that start with Y lean heavily on one single hue. Yellow alone accounts for more than a third of this entire letter group, calibrated seven separate ways by seven different naming authorities. Beyond that cluster sits a formal university blue and a genuinely modern pigment discovered by accident in a university lab.
This list of colors that start with Y only includes names with a real, checkable source. That means CSS/X11 standards, Crayola’s official naming, color-science systems like Munsell and NCS, and documented institutional colors. Every hex code here was checked against at least two sources before it made the list.
That checking mattered here. Some sites claim 127 or more colors that start with Y. Most of those extra names, things like “Yaffle Green” or “Yardbird,” came from a single fan-made source with no second reference confirming the hex code. Eighteen colors that start with Y survived real cross-checking, and every one is backed by a source you can verify yourself.
The list below groups colors that start with Y by family, then by real use. Designers will find seven distinct versions of Yellow here, each calibrated for a different purpose. Anyone curious about the newest color discovered by science will find YInMn Blue. Every entry in this guide of colors that start with Y is checkable and real.
Quick Answer: Standout Y Colors
Short on time? Here are eight standout colors that start with Y. Yellow (#FFFF00) is the pure CSS standard, bright and universally recognized. YInMn Blue (#2E5090) is a genuinely new pigment, discovered accidentally in a chemistry lab in 2009. Yale Blue (#00356B) delivers a deep, formal blue tied to over a century of university branding.

Yellow-Green (#9ACD32) provides a fresh, natural tone between two primary colors. Yankees Blue (#1C2841) offers a bold, near-black navy tied to one of baseball’s most storied teams. Yellow Ochre (#C6AE4E) rounds out the earthy end with a muted, traditional pigment. Yellow Rose (#FFF000) delivers a bright, cheerful yellow named after the flower. Yam (#CC6600) finishes the list with a warm, vegetable-inspired orange. Each of these colors that start with Y earns its spot through genuine, documented use.
What Y Colors Mean and Evoke
Color names carry emotional weight, and colors that start with Y lean overwhelmingly toward energy and optimism. Yellow suggests happiness and alertness more consistently across cultures than almost any other color, which is exactly why it shows up on caution signs and emergency vehicles worldwide. Its many calibrated variants, from Munsell to Pantone, all preserve that same core cheerfulness even as the exact shade shifts slightly.
Yale Blue and Yankees Blue both carry institutional weight instead, tied to specific universities and sports franchises rather than general emotion. These colors read as established and trustworthy precisely because they’ve stayed locked in place for over a century of consistent use.
YInMn Blue carries a different kind of significance entirely. Its meaning comes from novelty rather than tradition, representing genuine scientific discovery rather than centuries of accumulated cultural association. Yellow Ochre closes out this range with quiet earthiness, evoking clay and ancient pigment rather than anything bright or modern.
Color Families: Where Y Colors Belong

Yellows
Yellow, Yellow (Crayola), Yellow (Munsell), Yellow (NCS), Yellow (Pantone), Yellow (Process), Yellow (RYB), Yellow Rose, and Yellow Sunshine make up by far the largest family among colors that start with Y. The base Yellow stays the brightest and most saturated, while Yellow (Munsell) and Yellow (NCS) both pull slightly toward gold. Yellow Rose and Yellow Sunshine both lean warmer and more floral by comparison.
Blues
Yale Blue, Yale Blue (2005 official version), Yankees Blue, and YInMn Blue anchor this family. Yale Blue exists in two documented forms, since the university officially standardized its color in 2005, shifting it noticeably darker than the historic shade used since the 1850s. YInMn Blue stands apart entirely, the only color in this letter group created through genuine scientific accident rather than tradition.
Greens
Yellow-Green and Yellow-Green (Crayola) cover this smaller family among colors that start with Y. The standard version reads brighter and more saturated, while the Crayola version softens considerably into a paler, friendlier tone.
Oranges and Browns
Yam, Yellow Ochre, and Yellow Orange round out this warm family. Yam stays bold and saturated, closer to true orange, while Yellow Ochre pulls back into a muted, earthy pigment tone. Yellow Orange sits comfortably between the two, warm without tipping fully into either extreme.
Design & Branding Favorites
Certain colors that start with Y show up constantly in real branding work. Yellow and its many variants dominate caution signage, children’s branding, and anything wanting to project energy and visibility. Yale Blue and Yankees Blue both function as fixed institutional colors, rarely altered once locked into official use. YInMn Blue occasionally appears in cutting-edge, innovation-focused branding specifically because of its novel scientific origin.

Below is a quick reference for how four colors that start with Y typically get used in real design work. Notice how the yellow entries lean toward energy and visibility, while the blue entries lean toward institutional trust.
| Color | Hex | Typical Use |
| Yellow | #FFFF00 | Caution signage, energetic branding |
| Yale Blue | #00356B | University, institutional branding |
| Yankees Blue | #1C2841 | Sports team branding |
| YInMn Blue | #2E5090 | Innovation-focused, scientific branding |
Yellow and Yale Blue rarely appear together in the same palette, since one is built for maximum attention and the other for quiet formality. YInMn Blue works best as a distinctive accent, chosen specifically to signal something modern rather than traditional.
Fashion & Beauty Shades
Fashion and beauty brands often rely on a select group of colors that start with Y. These colors convey energy, optimism, and visibility in clothing, accessories, and cosmetics. These colors convey energy and visibility in packaging. Yellow Ochre is another popular choice, appreciated for its earthy character and natural warmth, making it a common feature in autumn-inspired collections, heritage branding, and rustic design themes. Yellow Rose adds a softer and more romantic touch, with its floral-inspired appearance frequently appearing in spring fashion, beauty campaigns, and gift-oriented branding. These shades offer warmth and personality, while deeper tones such as Yale Blue are typically used to convey sophistication, tradition, and a more formal visual identity.
Nature-Inspired Names
Several colors that start with Y borrow directly from the natural world. Yam takes its name and warm orange tone from the root vegetable, one of the more literal food-to-color connections in this letter group. Yellow Rose pulls from the flower, capturing its bright, cheerful color almost exactly.
Yellow-Green closes out this group with one of the more direct nature references on the list, matching the exact tone of new plant growth caught in bright sunlight. Yellow Ochre, meanwhile, connects to earth itself, originally derived from natural clay containing iron oxide, the same family of pigment used in prehistoric cave paintings.
Rare or Unusual Y Colors
Some colors that start with Y rarely surface outside specialist circles, but each has a real story behind it. YInMn Blue holds the most remarkable origin of any color in this entire series, discovered entirely by accident in 2009 when Oregon State University researchers were experimenting with manganese oxide for electronics applications and stumbled onto a brilliant, durable new blue pigment instead. It became the first new blue pigment discovered in over two hundred years.

Yale Blue carries its own documented complexity, existing in two distinct, separately recorded forms because the university didn’t formally standardize its shade until 2005, more than 150 years after Yale Crew first rowed in blue uniforms during the 1850s. Yankees Blue rounds out this group with a similarly specific institutional story, tied directly to one of the most recognized sports franchises in American history. Each of these colors that start with Y shows that “obscure” usually means “precisely documented,” not invented.
- YInMn Blue (#2E5090) — the first new blue pigment discovered in over 200 years
- Yale Blue (#00356B) — officially standardized only in 2005, after over 150 years of informal use
- Yankees Blue (#1C2841) — tied to one of baseball’s most storied franchises
- Yellow Ochre (#C6AE4E) — a pigment tradition dating back to prehistoric cave art
These four sit at the edge of common knowledge, but each one has a stable, checkable source. That’s what separates a genuinely rare color name from a vague one that different sites define inconsistently.
Colors Easily Confused With Each Other
A few pairs among colors that start with Y trip people up constantly. The two Yale Blue variants both read as deep, formal navy at a glance, but the 2005 official version runs noticeably darker and more saturated than the older, historic shade. Yellow-Green and Yellow-Green (Crayola) also cause confusion, since both share a name, but the Crayola version stays considerably paler and softer.

Yellow (Munsell) and Yellow (NCS) can also blur together, despite coming from entirely different color-science systems, since both pull slightly toward gold compared to the pure CSS standard. Yankees Blue and YInMn Blue sit in a similar dark-blue range too, though YInMn Blue carries noticeably more brightness and a distinct scientific origin.
The table below lines up the clearest pairs directly so the difference is easy to see at a glance. Pay attention to the RGB numbers, not just the names, since two colors that start with Y can look nearly identical in a small swatch but read differently once scaled up.
| Color A | Hex A | Color B | Hex B | Key Difference |
| Yale Blue (historic) | #0F4D92 | Yale Blue (2005 official) | #00356B | 2005 version is darker, more saturated |
| Yellow-Green | #9ACD32 | Yellow-Green (Crayola) | #C5E384 | Crayola version is far paler |
| Yellow (Munsell) | #EFCC00 | Yellow (NCS) | #FFD300 | NCS version leans more orange |
| Yankees Blue | #1C2841 | YInMn Blue | #2E5090 | YInMn Blue is noticeably brighter |
The two Yale Blue variants are the pair most likely to confuse someone doing university branding work, since both share the exact same name despite reading quite differently side by side. Yellow (Munsell) versus Yellow (NCS) matters most for anyone doing color-science or print work, since the wrong standard could shift a carefully planned yellow noticeably toward orange.
Master Alphabetical List of Y Colors
This list of colors that start with Y includes official CSS/X11 standards, Crayola-official names, color-science systems, and documented institutional colors. Standard CSS/X11 names are marked with an asterisk, since those carry a single, universally agreed hex code. Every other name below is still verified against its cited source.

- Yale Blue (historic) — #0F4D92
- Yale Blue (2005 official) — #00356B
- Yam — #CC6600
- Yankees Blue — #1C2841
- Yellow* — #FFFF00
- Yellow (Crayola) — #FCE883
- Yellow (Munsell) — #EFCC00
- Yellow (NCS) — #FFD300
- Yellow (Pantone) — #FEDF00
- Yellow (Process) — #FFEF00
- Yellow (RYB) — #FEFE33
- Yellow-Green* — #9ACD32
- Yellow-Green (Crayola) — #C5E384
- Yellow Ochre — #C6AE4E
- Yellow Orange — #FFAE42
- Yellow Rose — #FFF000
- Yellow Sunshine — #FFF700
- YInMn Blue — #2E5090
Notice how many of these colors that start with Y trace directly back to Yellow itself, seven separate variants alone. That concentration makes sense given how central yellow sits within the primary color wheel, prompting nearly every major naming authority to develop its own calibrated version.
Hex/RGB Crosswalk: Why Exact Codes Matter
A color name alone isn’t enough for real design work, even among colors that start with Y. Two designers using “yellow” without a hex code might land on seven noticeably different shades, since seven separate standards exist under that single name. That’s why any serious project needs the exact hex or RGB value locked in before production starts.
Hex codes matter most for web and app design, since browsers read hex values directly. RGB values matter more for video, screen graphics, and design software that calculates color mathematically. The table below gives both formats for five of the most frequently searched colors that start with Y, so you can copy whichever your tool requires.
| Color | Hex | RGB |
| Yellow | #FFFF00 | 255, 255, 0 |
| Yale Blue (2005) | #00356B | 0, 53, 107 |
| YInMn Blue | #2E5090 | 46, 80, 144 |
| Yellow-Green | #9ACD32 | 154, 205, 50 |
| Yam | #CC6600 | 204, 102, 0 |
Yellow’s RGB values max out both red and green while dropping blue entirely to zero, which is exactly what gives it that pure, electric brightness. Yale Blue, by contrast, keeps its red channel at zero while pushing blue only moderately, producing a deep, formal color rather than anything bright or saturated.

A few rows deserve a second look. The seven Yellow variants together form the largest single cluster of related names on this entire table, each calibrated independently by a different standards body. Yellow itself holds the most extreme RGB values here, maxing out two channels while zeroing the third. YInMn Blue stands out as the only entry with a documented discovery date, unlike every other color on this list drawn from tradition, nature, or institutional history.
Decision-Flow Table: Picking the Right Y Color
Choosing between eighteen distinct names gets easier with a clear project goal in mind. The table below matches common use cases to a recommended color that starts with Y, so you can skip the guesswork and go straight to a shade that fits the job.

| If you need… | Pick this color | Why |
| A bold, high-visibility design | Yellow or Yellow Sunshine | Impossible to miss, universally cheerful |
| A formal university identity | Yale Blue (2005 official) | Established, trustworthy, officially standardized |
| A sports or team branding project | Yankees Blue | Bold, storied, instantly recognizable |
