#643924 sits at 20° on the color wheel, placing it in the orange family of the warm half of the spectrum. With 47% saturation and 27% 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 100, 57, 36 produces a 9.76:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #643924 is a distant relative of CSS sienna — about 66 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 weight, depth, and grounded contrast. On screen the warm cast tends to pair best with cool neutrals around 210°-230° to balance temperature.
