#3F4528 sits at 72° on the color wheel, placing it in the yellow family of the warm half of the spectrum. With 27% saturation and 21% lightness, it reads as a softly muted, deep tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 63, 69, 40 produces a 10.03:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #3F4528 is a distant relative of CSS forest green — about 76 units away from #228B22. Designers reach for yellow hues at this saturation when the brief calls for restraint and atmosphere, 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.
