#81403D sits at 3° on the color wheel, placing it in the red family of the warm half of the spectrum. With 36% saturation and 37% lightness, it reads as a softly muted, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 129, 64, 61 produces a 7.68:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #81403D is a clear variant of CSS sienna — about 39 units away from #A0522D. Designers reach for red hues at this saturation when the brief calls for a conversational, mid-energy register, and at this lightness when they want a present, comfortable mid-canvas voice. On screen the warm cast tends to pair best with cool neutrals around 210°-230° to balance temperature.
