Palettes
What are Kelly Green Color Palette Codes?
Each of these is a hue rotation from #4CBB17. They are generated, not curated, so they are exact.
Complementary
Rotate a half turn and you land on #8617BB, a dark, saturated purple. Maximum hue distance, which is what makes a complement read as emphasis rather than decoration. Both are saturated, so give the complement much less area than the base or the two will fight.
Analogous
Step 30 degrees in each direction and you get #9EBB17 and #17BB34. Neighbouring hues hold together without effort, which is what makes analogous sets the safe choice for large areas.
Triadic
#174CBB and #BB174C 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: #3417BB and #BB179E. 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 #8617BB, and #179EBB with #BB3417. 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 Kelly Green 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
2.49:12.49
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
8.43:18.43
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 2.49:1 against white, Kelly Green 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 8.43:1.
Color vision
How Kelly Green 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#8A8B64
Kelly Green changes substantially here. ΔE 67.4
No working red cones. Reds darken sharply and drift toward the same muddy olive as green.
Deuteranopia
About 1% of men#847B6E
Kelly Green changes substantially here. ΔE 82.4
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#568187
Kelly Green changes substantially here. ΔE 86.2
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#A4A4A4
Kelly Green changes substantially here. ΔE 86.2
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, Kelly Green reads as #847B6E. That is a shift of ΔE 82.4, 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 tritanopia, at ΔE 86.2. 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.
