#0B3528 sits at 161° on the color wheel, placing it in the spring green family of the cool half of the spectrum. With 66% saturation and 13% lightness, it reads as a richly saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 11, 53, 40 produces a 13.51:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #0B3528 is a distant relative of CSS black — about 67 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.
