#42580F sits at 78° on the color wheel, placing it in the chartreuse family of the neutral half of the spectrum. With 71% saturation and 20% lightness, it reads as a richly saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 66, 88, 15 produces a 7.97:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #42580F is a distant relative of CSS forest green — about 63 units away from #228B22. Designers reach for chartreuse 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 balanced cast tends to pair best with either warm or cool accents depending on the surrounding palette.
