#0A8539 sits at 143° on the color wheel, placing it in the spring green family of the cool half of the spectrum. With 86% saturation and 28% lightness, it reads as a fully saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 10, 133, 57 produces a 4.74:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #0A8539 is a clear variant of CSS forest green — about 34 units away from #228B22. Designers reach for spring green 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 cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
