#890B11 sits at 357° on the color wheel, placing it in the red family of the warm half of the spectrum. With 85% saturation and 29% lightness, it reads as a fully saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 137, 11, 17 produces a 9.91:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #890B11 is a close cousin of CSS maroon — about 22 units away from #800000. Designers reach for red hues at this saturation when the brief calls for bold, immediate signal, and at this lightness when they want weight, depth, and grounded contrast. On screen the warm cast tends to pair best with cool neutrals around 210°-230° to balance temperature.
