Colors That Start With X: Beautiful, Rare Names & Codes
Colors that start with X make up the smallest, rarest group in the entire color-naming system. X is one of the least-used letters in English overall, and that scarcity shows up clearly once you try to document real, verifiable colors that start with X rather than just count them.
This guide only includes names with a real, checkable source. That means the same standard used throughout every letter in this series: a documented hex code confirmed across at least two independent references, not a single fan-made color chart. Every value here was checked this way before being included.
That checking mattered more for this letter than almost any other. Some sites claim 80 or even 85 colors that start with X. When we looked closely, most of those entries were the exact same base color repeated under different paint-brand names, things like “Xanadu (Dulux),” “Xanadu (Crown Paint),” and “Xanadu (Home Hardware),” each a slightly different regional tint of the same idea rather than a genuinely distinct, standardized color. Others, like a color reportedly “invented by” a random first name, came from a crowdsourced naming quiz rather than any recognized color authority. Two colors that start with X survived real verification, and both are backed by sources you can check yourself.
Quick Answer: The Standout X Colors
Given how few colors that start with X exist, the quick answer here is short but complete. Xanadu (#738678) is a grayish-green color documented directly in Wikipedia’s own reference article on shades of gray, giving it more formal recognition than almost any other name in this letter group. Xanthic (#EEED09) is a vivid, warm yellow tied to genuine chemistry terminology, distinct from Xanadu in both hue and origin.

Both names earn their place through documentation rather than volume. Where most letters in this series offer a dozen or more genuine options, colors that start with X offer exactly two that hold up to real scrutiny, which says as much about the English language as it does about color.
What X Colors Mean and Evoke
Color names carry emotional weight, and even a group this small carries real meaning. Xanadu takes its name from the legendary, opulent city described in Samuel Taylor Coleridge’s poem “Kubla Khan,” a place associated with mystery, luxury, and something just out of reach. That poetic weight explains why the color itself, a muted, sophisticated gray-green, reads as calm and slightly enigmatic rather than bold or cheerful.
Xanthic carries an entirely different mood, tied to the Greek root “xanthos,” meaning yellow or golden. Unlike Xanadu’s literary mystery, Xanthic leans scientific and precise, a term still used today in chemistry to describe certain yellow compounds. Where Xanadu suggests imagination, Xanthic suggests observation and classification, a color named for what it clearly and simply is.
Color Families: Where X Colors Belong
Gray-Greens
Xanadu stands alone in this family, and it’s the only entry in this entire letter group that falls anywhere close to a neutral. Its grayish-green tone sits comfortably between true gray and muted olive, making it useful as a sophisticated, understated accent rather than a bold statement color.
Yellows
Xanthic occupies this family by itself, a vivid, warm yellow with genuine chemistry ties. Unlike softer, pastel yellows found in other letter groups throughout this series, Xanthic reads as bright and attention-grabbing, closer to a true, saturated yellow than anything muted.
Given that these two colors that start with X sit in entirely different families, they don’t naturally group into a shared palette on their own. Anyone wanting to build a complete color scheme around this letter would need to pull complementary shades from elsewhere in the alphabet.
Design & Branding Favorites
With only two documented colors that start with X, design use stays narrow but genuine. Xanadu shows up occasionally in sophisticated, understated branding, chosen specifically because its muted gray-green avoids feeling either cold or overly organic. Xanthic, by contrast, rarely appears in mainstream branding at all, staying mostly within scientific and technical contexts where its precise, chemistry-linked meaning matters more than its visual appeal.

Below is a quick reference for how each of these colors that start with X typically gets used in real-world contexts. Notice how differently the two entries function, one leaning toward calm sophistication and the other toward technical precision.
| Color | Hex | Typical Use |
| Xanadu | #738678 | Sophisticated, understated branding |
| Xanthic | #EEED09 | Scientific and technical contexts |
Xanadu works well as a supporting neutral in a broader palette, pairing naturally with warmer earth tones or cooler blues. Xanthic, given its narrower real-world use, functions best as a specific technical reference rather than a general design choice.
Fashion & Beauty Shades
Fashion draws almost nothing from colors that start with X directly, which sets this letter apart from nearly every other group in this series. Xanadu occasionally appears in muted, sophisticated fall or winter color stories, since its grayish-green reads as calm and versatile rather than seasonal or trendy. Its understated quality means it rarely serves as a headline color, instead working quietly alongside more prominent shades.
Xanthic has essentially no documented presence in fashion or beauty branding, staying almost entirely within its scientific and technical origins. That absence isn’t a gap in research; it genuinely reflects how the color has been used historically, favoring chemistry textbooks over runway collections.
Nature-Inspired Names
Neither of the two colors that start with X ties directly to a plant, animal, or landscape feature, which again sets this letter apart from most others in this series. Xanadu draws its name from literature rather than nature, referencing a fictional, idealized city rather than anything physically observable. Xanthic, despite its chemistry association, ultimately traces back to a Greek word for a color quality rather than any specific natural object.
This absence of nature-based naming reflects the letter’s overall scarcity more than anything else. With so few words of any kind beginning with X in English, the handful that exist tend to come from literature, science, or borrowed terminology rather than the everyday natural-world vocabulary that shapes color names in richer letter groups.
Rare or Unusual X Colors
Given that this entire letter group contains only two verified entries, both could reasonably be called rare simply by existing. Xanadu deserves particular attention for its literary pedigree, tied directly to Coleridge’s 1797 poem “Kubla Khan,” one of English literature’s most famous unfinished works. That connection gives the color a documented cultural weight far beyond its muted, understated appearance.

Xanthic carries its own specific story, rooted in 19th-century chemistry terminology used to describe certain sulfur-containing yellow compounds. The word predates most modern color-naming systems entirely, surviving into design use as one of the few genuinely old, scientifically grounded color terms that happens to start with X.
- Xanadu (#738678) — named after the legendary city in Coleridge’s poem “Kubla Khan”
- Xanthic (#EEED09) — rooted in 19th-century chemistry terminology for yellow compounds
These two names represent the entire documented, verifiable set of colors that start with X. That’s a stark contrast to letters elsewhere in this series with fifty or more entries, and it’s a direct, honest reflection of how rarely English words of any kind begin with this particular letter.
Colors Easily Confused With Each Other
With only two entries in this letter group, there isn’t a genuinely confusable pair among colors that start with X. Xanadu and Xanthic sit in completely different color families, one a muted gray-green and the other a bright, saturated yellow, so mixing them up visually would be difficult even for someone unfamiliar with either name.
The more realistic confusion comes from outside sources rather than between the two entries themselves. Several paint manufacturers sell products labeled “Xanadu” with noticeably different hex codes from the documented, Wikipedia-referenced version used in this guide. Anyone searching for this color should confirm which specific “Xanadu” a source means, since brand-specific tints can shift the actual shade considerably from the standard, cross-verified value.
| Color A | Hex A | Note |
| Xanadu (this guide) | #738678 | Cross-verified, Wikipedia-documented |
| Xanadu (various paint brands) | Varies widely | Regional tints, not independently verified |
This table exists specifically to flag that risk rather than to compare two genuinely confusable colors that start with X. If a project requires an exact, dependable Xanadu shade, the documented #738678 value used throughout this guide is the safest, most cross-verified choice available.
Master List of X Colors
This short list includes every color that starts with X that survived cross-checking against at least two independent, reliable sources. Given the extreme rarity of this letter, there’s no meaningful split between common names and brand-specific ones here, since both entries come from broad, general documentation rather than any single company or design house.

- Xanadu — #738678
- Xanthic — #EEED09
That’s the complete, honestly verified list. Readers searching for a longer roster of colors that start with X should treat any source claiming otherwise with real skepticism, since the additional names typically trace back to a single unverified paint-brand variant or a crowdsourced naming submission rather than genuine, cross-checked documentation.
Hex/RGB Crosswalk: Why Exact Codes Matter
A color name alone isn’t enough for real design work, and that holds true even for a letter with only two entries. Someone searching for “Xanadu” without a hex code might land on any of several noticeably different paint-brand interpretations rather than the documented, cross-verified shade. 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 the two colors that start with X, covering the complete list in one place.
| Color | Hex | RGB |
| Xanadu | #738678 | 115, 134, 120 |
| Xanthic | #EEED09 | 238, 237, 9 |
Xanadu’s RGB values stay close together across all three channels, which is exactly what produces its muted, grayish quality rather than anything vivid. Xanthic sits at the opposite extreme, with red and green both pushed high while blue drops to nearly zero, giving it that bright, warm yellow intensity.
Full Comparison Table: All Verified X Colors
This table brings both colors that start with X together with hex, RGB, color family, and common use in one place. Given how short this list is, treat this table as the complete, authoritative reference rather than one section among many.

| Color | Hex | RGB | Family | Common Use |
| Xanadu | #738678 | 115, 134, 120 | Gray-Green | Sophisticated, understated branding |
| Xanthic | #EEED09 | 238, 237, 9 | Yellow | Scientific and technical reference |
These two entries couldn’t sit further apart on the color wheel, which actually makes them useful as a study in contrast. Xanadu offers restraint and neutrality, while Xanthic offers brightness and specificity, and together they represent the full, honestly documented range of colors that start with X.
Decision-Flow Table: Picking the Right X Color
Choosing between colors that start with X is refreshingly simple, since there are only two documented options to consider. The table below matches each color to its most natural use case, so the decision comes down to project type rather than sorting through dozens of similar names.

| If you need… | Pick this color | Why |
| A sophisticated, muted accent | Xanadu | Calm, understated, literary pedigree |
| A precise scientific or technical reference | Xanthic | Rooted in genuine chemistry terminology |
Given how limited this letter is, most real-world projects will pull the majority of their palette from other letters entirely, using Xanadu or Xanthic as a single distinctive touch rather than a foundation. Pairing Xanadu with a warmer neutral, or using Xanthic sparingly as a bright accent, both work well within a broader color scheme built elsewhere.
Conclusion
Colors that start with X make up the smallest, most limited group in this entire series, but the two entries that survive real verification carry genuine documentation and history. This guide sticks to Xanadu and Xanthic, both backed by real hex and RGB codes, so nothing here is guesswork or padding. Whether you’re curious why this letter is so limited or looking for one distinctive accent color, these colors that start with X give you an honest, checkable answer.
