Palettes
What are Zaffre Color Palette Codes?
Each of these is a hue rotation from #0014A8. They are generated, not curated, so they are exact.
Complementary
The opposite hue is #A89400, a mid-tone, vivid yellow. Complements carry the strongest contrast of any two-color scheme, so this pair suits a call to action better than a background. Both are saturated, so give the complement much less area than the base or the two will fight.
Analogous
Its two neighbours are #0068A8 and #4000A8. Because they overlap heavily in hue, nothing in the group competes, and the eye reads the whole set as a single color with variation.
Triadic
#A80014 and #14A800 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: #A84000 and #68A800. 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 #A89400, and #A80068 with #00A840. 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 Zaffre 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
12.61:112.61
contrast ratio on white 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 |
Black background
1.67:11.67
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 | Fails | Fails |
| UI component needs 3:1 | Fails | n/a |
Zaffre clears WCAG AA against white at 12.61:1, so it is safe for body copy as well as headings. Text placed on it should be white, which gives 12.61:1. It is a highly saturated color, so it will dominate anything it sits beside. Give it space rather than surrounding it with other strong colors.
Color vision
How Zaffre 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#0A0A95
Zaffre shifts slightly here. ΔE 6.9
No working red cones. Reds darken sharply and drift toward the same muddy olive as green.
Deuteranopia
About 1% of men#09078F
Zaffre shifts slightly here. ΔE 9.2
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#01827E
Zaffre changes substantially here. ΔE 111.0
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#333333
Zaffre changes substantially here. ΔE 91.7
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, Zaffre reads as #09078F. That is a shift of ΔE 9.2, so it is a different color to roughly one man in sixteen. Blues survive red-green deficiency well, which is why so much interface design leans on them. The form to watch here is tritanopia, though at roughly 1 in 10,000 it affects far fewer people. The widest shift is under tritanopia, at ΔE 111.0. 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.
