Blue Green Color CIELChuv Code
The Blue Green CIELCHuv code is 47.19, 37.24, 170.40°. Unlike hex or RGB this one is perceptual: lightness 47 means mid-toned to the eye rather than to the screen, and chroma 37 is how far it sits from grey.

Palettes
What are Blue Green Color Palette Codes?
Each of these is a hue rotation from #137E6D. They are generated, not curated, so they are exact.
Complementary
Rotate a half turn and you land on #7E1324, a dark, saturated red. 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 #137E38 and #135A7E. Neighbouring hues hold together without effort, which is what makes analogous sets the safe choice for large areas.
Triadic
#6D137E and #7E6D13 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: #7E135A and #7E3813. 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 #7E1324, and #38137E with #5A7E13. 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 Blue 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
4.96:14.96
contrast ratio on white background
| Element | AA | AAA |
|---|---|---|
| Small text needs 4.5:1 / 7:1 | Passes | Fails |
| Large text needs 3:1 / 4.5:1 | Passes | Passes |
| UI component needs 3:1 | Passes | n/a |
Black background
4.23:14.23
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 | Passes | Fails |
| UI component needs 3:1 | Passes | n/a |
Blue Green clears WCAG AA against white at 4.96:1, so it is safe for body copy as well as headings. Text placed on it should be white, which gives 4.96:1.
Color vision
How Blue 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#565771
Blue Green changes substantially here. ΔE 42.6
No working red cones. Reds darken sharply and drift toward the same muddy olive as green.
Deuteranopia
About 1% of men#514972
Blue Green changes substantially here. ΔE 53.4
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#237575
Blue Green shifts noticeably here. ΔE 12.3
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#707070
Blue Green changes substantially here. ΔE 32.6
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, Blue Green reads as #514972. That is a shift of ΔE 53.4, so it is a different color to roughly one man in sixteen. The widest shift is under deuteranopia, at ΔE 53.4. 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.
