#664C1D sits at 39° on the color wheel, placing it in the orange family of the warm half of the spectrum. With 56% saturation and 26% 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 102, 76, 29 produces a 8.03:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #664C1D is a distant relative of CSS sienna — about 60 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.
