Canary Yellow Color CIELChuv Code
The Canary Yellow CIELCHuv code is 93.01, 102.57, 79.66°. Unlike hex or RGB this one is perceptual: lightness 93 means light to the eye rather than to the screen, and chroma 103 is how far it sits from grey.

What are Canary Yellow Color Palette Codes?
Each of these is a hue rotation from #FFEF00. They are generated, not curated, so they are exact.
Complementary
Directly opposite sits #0010FF, a dark, vivid blue. No other pairing separates two hues further, so this is the one to reach for when a single element has to win attention. Both are saturated, so give the complement much less area than the base or the two will fight.
Analogous
#FF7000 and #90FF00 sit 30 degrees either side. All three share most of their hue, so the set reads as one family instead of three separate decisions. Good for backgrounds and for state variations that should not announce themselves.
Triadic
#00FFEF and #EF00FF 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: #0090FF and #7000FF. 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 #0010FF, and #00FF70 with #FF0090. 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 Canary Yellow 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
1.19:11.19
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
17.60:117.60
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 1.19:1 against white, Canary Yellow 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 17.60:1. 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 Canary Yellow 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#F8F87E
Canary Yellow changes substantially here. ΔE 33.7
No working red cones. Reds darken sharply and drift toward the same muddy olive as green.
Deuteranopia
About 1% of men#F9FA8B
Canary Yellow changes substantially here. ΔE 38.8
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#FEA5AC
Canary Yellow changes substantially here. ΔE 95.7
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#EBEBEB
Canary Yellow changes substantially here. ΔE 92.5
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, Canary Yellow reads as #F9FA8B. That is a shift of ΔE 38.8, so it is a different color to roughly one man in sixteen. The widest shift is under tritanopia, at ΔE 95.7. 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.
