What are Baby Blue Color Palette Codes?
Each of these is a hue rotation from #89CFF0. They are generated, not curated, so they are exact.
Complementary
The opposite hue is #F0AA89, a light, saturated red-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 #89F0DE and #899CF0. 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
#F089CF and #CFF089 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: #F0899C and #F0DE89. 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 #F0AA89, and #DE89F0 with #9CF089. 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 Baby Blue 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
1.71:11.71
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
12.25:112.25
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 1.71:1 against white, Baby 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 12.25:1.
Color vision
How Baby 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#ACADE9
Baby Blue changes substantially here. ΔE 28.0
No working red cones. Reds darken sharply and drift toward the same muddy olive as green.
Deuteranopia
About 1% of men#A8A2E7
Baby Blue changes substantially here. ΔE 34.1
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#8EE2E1
Baby Blue shifts noticeably here. ΔE 20.3
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#C6C6C6
Baby Blue changes substantially here. ΔE 26.8
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, Baby Blue reads as #A8A2E7. That is a shift of ΔE 34.1, 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 deuteranopia, at ΔE 34.1. 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.
