CMYK is a standard screen-to-print conversion. Printed results depend on inks, paper and color profiles.

What is Dark Cyan?

Dark Cyan is one of the named colors defined by the CSS Color specifications (keyword “darkcyan”), so every modern browser understands it without a hex code.

Its hue angle of 180° places it in the cyan part of the color wheel, with 100% saturation (vivid) and 27% lightness (dark). It is a cool color.

Compared with the other cyan / teal colors in the Aqeeb Studio library, it is lighter than 27% of them and more saturated than 62% of them.

Its relative luminance is 0.203, which makes it a mid-tone color. That is above the 0.179 crossover point at which black and white text have equal contrast, so black text has the advantage.

Dark Cyan counts as a light color: its HSL lightness is 27% and its relative luminance is 0.203. Black text reads best on it (5.06:1 contrast).

Dark Magenta#8B008B ≈ Olive#8B8B00

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.

≈ Mulberry#8B0046 ≈ Warm Brown#8B4600

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.

Monochromatic variants
