#138B01 sits at 112° on the color wheel, placing it in the green family of the cool half of the spectrum. With 99% saturation and 27% lightness, it reads as a fully saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 19, 139, 1 produces a 4.72:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #138B01 is a close cousin of CSS green — about 22 units away from #008000. Designers reach for 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.
