#240A3A sits at 273° on the color wheel, placing it in the violet family of the cool half of the spectrum. With 71% saturation and 13% lightness, it reads as a richly saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 36, 10, 58 produces a 17.80:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #240A3A is a distant relative of CSS black — about 69 units away from #000000. Designers reach for violet 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 cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
