#273D01 sits at 82° on the color wheel, placing it in the chartreuse family of the neutral half of the spectrum. With 97% saturation and 12% lightness, it reads as a fully saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 39, 61, 1 produces a 11.97:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #273D01 is a distant relative of CSS black — about 72 units away from #000000. Designers reach for chartreuse 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 balanced cast tends to pair best with either warm or cool accents depending on the surrounding palette.
