Palettes

What are Eerie Black Color Palette Codes?

Each of these is a hue rotation from #1B1B1B. They are generated, not curated, so they are exact.

Complementary

Directly opposite sits #1B1B1B, a very dark neutral grey. No other pairing separates two hues further, so this is the one to reach for when a single element has to win attention. Neither is especially saturated, so this pairing stays calm enough for large areas of both.

Analogous

#1B1B1B and #1B1B1B 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

#1B1B1B and #1B1B1B 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: #1B1B1B and #1B1B1B. 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 #1B1B1B, and #1B1B1B with #1B1B1B. 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

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.

Eerie Black clears WCAG AA against white at 17.22:1, so it is safe for body copy as well as headings. Text placed on it should be white, which gives 17.22:1. With very little saturation it behaves as a neutral, which makes it a good background or a supporting tone alongside a stronger accent.

Color vision

How Eerie Black 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

#1B1B1B

Eerie Black holds up almost unchanged here. ΔE 0.0

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

Deuteranopia

About 1% of men

actual

#1B1B1B

Eerie Black holds up almost unchanged here. ΔE 0.0

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

#1B1B1B

Eerie Black holds up almost unchanged here. ΔE 0.0

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

#1B1B1B

Eerie Black holds up almost unchanged here. ΔE 0.0

No color vision at all. Also a fair proxy for how the color survives a greyscale print or a failing screen.

Eerie Black is stable under the common forms of color blindness: to a deuteranope it reads as #1B1B1B, a shift of only ΔE 0.0, which is close to imperceptible. The widest shift is under protanopia, at ΔE 0.0. 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.
