#667E05 sits at 72° on the color wheel, placing it in the yellow family of the warm half of the spectrum. With 92% saturation and 26% lightness, it reads as a fully saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 102, 126, 5 produces a 4.61:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #667E05 is a clear variant of CSS olive — about 27 units away from #808000. Designers reach for yellow hues at this saturation when the brief calls for bold, immediate signal, 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.
