What is Blood?

“Blood” is a crowd-sourced name from the XKCD Color Survey, in which participants typed names for colors they were shown. It is a popular everyday label rather than an official standard.

Its hue angle of 359° places it in the red part of the color wheel, with 100% saturation (vivid) and 23% lightness (dark). It is a warm color.

Compared with the other red colors in the Aqeeb Studio library, it is lighter than 10% of them and more saturated than 67% of them.

Its relative luminance is 0.039, which makes it a dark color. That is below the 0.179 crossover point at which black and white text have equal contrast, so white text has the advantage.

Colors that go with Blood

Complementary color

≈ Deep Turquoise#007776

Analogous colors

Analogous colors are neighbors on the wheel, 30° either side of the base hue. They blend smoothly and are easy to combine in backgrounds, gradients and illustrations.

≈ Merlot#77003C ≈ Saddle Brown#773A00

Triadic colors

A triadic scheme uses three hues spaced 120° apart. It is lively yet balanced, and works best when one color leads and the other two act as accents.

≈ Green#017700 ≈ Deep Blue#000177

Split-complementary colors

Split-complementary keeps the base color and uses the two colors on either side of its complement (150° and 210°). The contrast is strong but gentler than a direct complement.

≈ Jungle Green#00773A ≈ Twilight Blue#003D77

Tetradic colors

A tetradic (rectangle) scheme combines two complementary pairs at 0°, 60°, 180° and 240°. It offers variety but needs one dominant color to stay balanced.

≈ Olive#777600 ≈ Deep Turquoise#007776 ≈ Deep Blue#000177

Monochromatic variants

Monochromatic variants keep the same hue and saturation and only change lightness, which makes them dependable for UI scales and subtle layered designs.
