#B1643D sits at 20° on the color wheel, placing it in the orange family of the warm half of the spectrum. With 49% saturation and 47% lightness, it reads as a moderately saturated, balanced tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 177, 100, 61 produces a 4.76:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #B1643D is a clear variant of CSS sienna — about 29 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.
