#666431 sits at 58° on the color wheel, placing it in the yellow family of the warm half of the spectrum. With 35% saturation and 30% 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 102, 100, 49 produces a 6.12:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #666431 is a clear variant of CSS olive drab — about 45 units away from #6B8E23. Designers reach for yellow 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.
