#0B0E03 sits at 76° on the color wheel, placing it in the chartreuse family of the neutral half of the spectrum. With 65% saturation and 3% lightness, it reads as a richly saturated, near-black tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 11, 14, 3 produces a 19.47:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #0B0E03 is a close cousin of CSS black — about 18 units away from #000000. Designers reach for chartreuse 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 balanced cast tends to pair best with either warm or cool accents depending on the surrounding palette.
