#81553C sits at 22° on the color wheel, placing it in the orange family of the warm half of the spectrum. With 37% 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, 85, 60 produces a 6.37:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #81553C is a clear variant of CSS sienna — about 35 units away from #A0522D. Designers reach for orange 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.
