#0D3420 sits at 149° on the color wheel, placing it in the spring green family of the cool half of the spectrum. With 60% saturation and 13% lightness, it reads as a moderately saturated, deep tone — a near-black anchor suited to grounding heavier compositions. Its RGB mix of 13, 52, 32 produces a 13.73:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #0D3420 is a distant relative of CSS black — about 62 units away from #000000. 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.
