Jasper Color Hex Code
The Jasper color hex code is #D73B3E. Those six digits are three pairs, D7 for red, 3B for green and 3E for blue, which is the same triplet a browser reads from the CSS value below.

Jasper Color HSV Code
The Jasper HSV code is 359°, 73%, 84%. Read it as a hue of 359 degrees, 73% saturation and 84% value, which is the form most color pickers use because moving one number changes one thing.

Jasper Color CIELChuv Code
The Jasper CIELCHuv code is 49.41, 121.06, 11.65°. Unlike hex or RGB this one is perceptual: lightness 49 means mid-toned to the eye rather than to the screen, and chroma 121 is how far it sits from grey.

Palettes
What are Jasper Color Palette Codes?
Each of these is a hue rotation from #D73B3E. They are generated, not curated, so they are exact.
Complementary
Half a turn away is #3BD7D4, a light, saturated teal. This is the widest separation the wheel offers, and the reason complementary pairs are the default for anything that must stand out. Neither is especially saturated, so this pairing stays calm enough for large areas of both.
Analogous
Either side sit #D73B8C and #D7863B, 30 degrees out. Low tension by construction: useful when you need several related tones that still feel like one choice.
Triadic
#3ED73B and #3B3ED7 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: #3BD786 and #3B8CD7. 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 #3BD7D4, and #8CD73B with #863BD7. 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 Jasper 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
4.58:14.58
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
4.58:14.58
contrast ratio on black 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 |
Jasper clears WCAG AA against white at 4.58:1, so it is safe for body copy as well as headings. Text placed on it should be black, which gives 4.58:1.
Color vision
How Jasper 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#AAA93D
Jasper changes substantially here. ΔE 78.1
No working red cones. Reds darken sharply and drift toward the same muddy olive as green.
Deuteranopia
About 1% of men#B1BA3D
Jasper changes substantially here. ΔE 86.2
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#D23D3D
Jasper holds up almost unchanged here. ΔE 2.4
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#757575
Jasper changes substantially here. ΔE 69.6
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, Jasper reads as #B1BA3D. That is a shift of ΔE 86.2, 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 86.2. 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.
