#8F543B sits at 18° on the color wheel, placing it in the orange family of the warm half of the spectrum. With 42% saturation and 40% lightness, it reads as a moderately saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 143, 84, 59 produces a 6.00:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #8F543B is a close cousin of CSS sienna — about 22 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.
