#135F3F sits at 155° on the color wheel, placing it in the spring green family of the cool half of the spectrum. With 67% saturation and 22% lightness, it reads as a richly saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 19, 95, 63 produces a 7.67:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #135F3F is a clear variant of CSS forest green — about 55 units away from #228B22. Designers reach for spring 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.
