#400B31 sits at 317° on the color wheel, placing it in the rose family of the neutral half of the spectrum. With 71% saturation and 15% lightness, it reads as a richly saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 64, 11, 49 produces a 16.03:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #400B31 is a distant relative of CSS maroon — about 81 units away from #800000. Designers reach for rose 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 balanced cast tends to pair best with either warm or cool accents depending on the surrounding palette.
