#2A731B sits at 110° on the color wheel, placing it in the green family of the cool half of the spectrum. With 62% saturation and 28% lightness, it reads as a moderately saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 42, 115, 27 produces a 5.89:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #2A731B is a clear variant of CSS forest green — about 26 units away from #228B22. Designers reach for green 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 cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
