Ebony Color CIELChuv Code
The Ebony CIELCHuv code is 38.44, 9.56, 113.38°. Unlike hex or RGB this one is perceptual: lightness 38 means mid-toned to the eye rather than to the screen, and chroma 10 is how far it sits from grey.

Palettes
What are Ebony Color Palette Codes?
Each of these is a hue rotation from #555D50. They are generated, not curated, so they are exact.
Complementary
Rotate a half turn and you land on #58505D, a dark neutral grey. Maximum hue distance, which is what makes a complement read as emphasis rather than decoration. Neither is especially saturated, so this pairing stays calm enough for large areas of both.
Analogous
Step 30 degrees in each direction and you get #5C5D50 and #505D52. Neighbouring hues hold together without effort, which is what makes analogous sets the safe choice for large areas.
Triadic
#50555D and #5D5055 complete an even 120 degree split. Three fully independent hues, so one has to lead: keep this base dominant and let the other two appear in small quantities.
Split-complementary
Instead of the direct complement, this takes the two hues either side of it: #52505D and #5D505C. Almost the same contrast, without the edge shimmer a true complementary pair produces at high saturation.
Tetradic
Two complementary pairs forming a rectangle: this base with #58505D, and #505C5D with #5D5250. The richest of the five and the hardest to balance, so treat this base as the lead and hold the other three well back.
Accessibility
Contrast checker: is Ebony accessible?
Measured against white and against black, with a separate verdict for each element type. Small text, large text and UI components have different thresholds, so one pass or fail for the whole color would be wrong roughly a third of the time.
White background
6.85:16.85
contrast ratio on white background
| Element | AA | AAA |
|---|---|---|
| Small text needs 4.5:1 / 7:1 | Passes | Fails |
| Large text needs 3:1 / 4.5:1 | Passes | Passes |
| UI component needs 3:1 | Passes | n/a |
Black background
3.07:13.07
contrast ratio on black background
| Element | AA | AAA |
|---|---|---|
| Small text needs 4.5:1 / 7:1 | Fails | Fails |
| Large text needs 3:1 / 4.5:1 | Passes | Fails |
| UI component needs 3:1 | Passes | n/a |
Ebony clears WCAG AA against white at 6.85:1, so it is safe for body copy as well as headings. Text placed on it should be white, which gives 6.85:1. With very little saturation it behaves as a neutral, which makes it a good background or a supporting tone alongside a stronger accent.
Color vision
How Ebony looks with color blindness
Around 300 million people see color differently from the way it is specified. Each card shows the actual color beside how it appears, and how common that form of vision is.
Protanopia
About 1% of men#595953
Ebony shifts slightly here. ΔE 5.5
No working red cones. Reds darken sharply and drift toward the same muddy olive as green.
Deuteranopia
About 1% of men#585754
Ebony shifts slightly here. ΔE 7.4
No working green cones. With the milder deuteranomaly at nearer 6% of men, this is by far the most common form, and the one worth designing around.
Tritanopia
About 1 in 10,000#555656
Ebony shifts slightly here. ΔE 8.8
No working blue cones. Blues shift toward green and yellows toward pink. Rare, and unlike the others it is not sex-linked, so it affects men and women equally.
Achromatopsia
About 1 in 30,000#5A5A5A
Ebony shifts slightly here. ΔE 8.7
No color vision at all. Also a fair proxy for how the color survives a greyscale print or a failing screen.
To a deuteranope, the most common form, Ebony reads as #585754. That is a shift of ΔE 7.4, so it is a different color to roughly one man in sixteen. The widest shift is under tritanopia, at ΔE 8.8. The rule this leads to needs no simulator: never let color be the only thing carrying a message. Add a label, an icon, or a clear difference in lightness, and the problem disappears for everyone.
