#39330D sits at 52° on the color wheel, placing it in the yellow family of the warm half of the spectrum. With 63% saturation and 14% lightness, it reads as a moderately saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 57, 51, 13 produces a 12.70:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #39330D is a distant relative of CSS black — about 78 units away from #000000. 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.
