Palettes

What are Cornflower Blue Color Palette Codes?

Each of these is a hue rotation from #6495ED. They are generated, not curated, so they are exact.

Complementary

The opposite hue is #EDBC64, a light, saturated orange. 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 #64DAED and #7864ED. 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

#ED6495 and #95ED64 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: #ED7864 and #DAED64. 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 #EDBC64, and #ED64DA with #64ED78. 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

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.

contrast ratio on white background

Element	AA	AAA

At 2.97:1 against white, Cornflower Blue 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 7.06:1.

Color vision

How Cornflower Blue 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

actual

#7C7DDC

Cornflower Blue shifts noticeably here. ΔE 15.4

No working red cones. Reds darken sharply and drift toward the same muddy olive as green.

Deuteranopia

About 1% of men

actual

#7975D7

Cornflower Blue shifts noticeably here. ΔE 18.8

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

actual

#67CDCA

Cornflower Blue changes substantially here. ΔE 59.4

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

actual

#969696

Cornflower Blue changes substantially here. ΔE 50.2

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, Cornflower Blue reads as #7975D7. That is a shift of ΔE 18.8, 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 59.4. 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.

Meaning
