#40390E sits at 52° on the color wheel, placing it in the yellow family of the warm half of the spectrum. With 64% saturation and 15% lightness, it reads as a moderately saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 64, 57, 14 produces a 11.60:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #40390E is a distant relative of CSS maroon — about 87 units away from #800000. 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 weight, depth, and grounded contrast. On screen the warm cast tends to pair best with cool neutrals around 210°-230° to balance temperature.
