Celadon Color HSV Code

Celadon Color CIELChuv Code
The Celadon CIELCHuv code is 84.85, 41.61, 129.49°. Unlike hex or RGB this one is perceptual: lightness 85 means light to the eye rather than to the screen, and chroma 42 is how far it sits from grey.

Palettes
What are Celadon Color Palette Codes?
Each of these is a hue rotation from #ACE1AF. They are generated, not curated, so they are exact.
Complementary
Rotate a half turn and you land on #E1ACDE, a light, muted purple. 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 #C4E1AC and #ACE1CA. Neighbouring hues hold together without effort, which is what makes analogous sets the safe choice for large areas.
Triadic
#AFACE1 and #E1AFAC 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: #CAACE1 and #E1ACC4. 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 #E1ACDE, and #ACC4E1 with #E1CAAC. The richest of the five and the hardest to balance, so treat the darkest of the four as the lead and hold the other three well back.
Accessibility
Contrast checker: is Celadon 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
1.48:11.48
contrast ratio on white background
| Element | AA | AAA |
|---|---|---|
| Small text needs 4.5:1 / 7:1 | Fails | Fails |
| Large text needs 3:1 / 4.5:1 | Fails | Fails |
| UI component needs 3:1 | Fails | n/a |
Black background
14.14:114.14
contrast ratio on black background
| Element | AA | AAA |
|---|---|---|
| Small text needs 4.5:1 / 7:1 | Passes | Passes |
| Large text needs 3:1 / 4.5:1 | Passes | Passes |
| UI component needs 3:1 | Passes | n/a |
At 1.48:1 against white, Celadon is a fill color rather than a text color. Use it for surfaces, borders and large display type, and set the copy in ink. Text placed on it should be black, which gives 14.14:1.
Color vision
How Celadon 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#C5C6BD
Celadon changes substantially here. ΔE 29.2
No working red cones. Reds darken sharply and drift toward the same muddy olive as green.
Deuteranopia
About 1% of men#C2BEC0
Celadon changes substantially here. ΔE 35.3
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#AFC7C9
Celadon changes substantially here. ΔE 30.3
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#D4D4D4
Celadon changes substantially here. ΔE 32.7
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, Celadon reads as #C2BEC0. That is a shift of ΔE 35.3, so it is a different color to roughly one man in sixteen. It sits in the green range, the other half of the red-green pair. Against a red of similar lightness it will not read as distinct, so anything depending on that contrast needs a second cue. The widest shift is under deuteranopia, at ΔE 35.3. 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.
