Zarqa Color CIELChuv Code

The Zarqa CIELCHuv code is 57.58, 157.74, 16.76°. Unlike hex or RGB this one is perceptual: lightness 58 means mid-toned to the eye rather than to the screen, and chroma 158 is how far it sits from grey.

Palettes

What are Zarqa Color Palette Codes?

Each of these is a hue rotation from #FF4500. They are generated, not curated, so they are exact.

Complementary

Directly opposite sits #00BAFF, a light, vivid azure 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

#FF003B and #FFC500 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

#00FF45 and #4500FF 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: #00FFC5 and #003BFF. 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 #00BAFF, and #3BFF00 with #C500FF. 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 Zarqa 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.

Against white Zarqa reaches 3.44:1, enough for large text and UI borders, but short of the 4.5:1 that body copy needs. Darken it for anything set small. Text placed on it should be black, which gives 6.10:1. 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 Zarqa 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

#CAC920

Zarqa changes substantially here. ΔE 87.7

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

Deuteranopia

About 1% of men
actual

#D2DC24

Zarqa changes substantially here. ΔE 95.1

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
actual

#FA2D2F

Zarqa shifts noticeably here. ΔE 19.6

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

#8A8A8A

Zarqa changes substantially here. ΔE 96.7

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, Zarqa reads as #D2DC24. That is a shift of ΔE 95.1, so it is a different color to roughly one man in sixteen. It sits in the red end of the spectrum, which is exactly where red-green deficiency does its damage. Never pair it with a green of similar lightness to signal a difference in meaning: to a large minority the two become one color. The widest shift is under deuteranopia, at ΔE 95.1. 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.
