#2B155E sits at 258° on the color wheel, placing it in the violet family of the cool half of the spectrum. With 63% saturation and 23% lightness, it reads as a moderately saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 43, 21, 94 produces a 15.31:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #2B155E is a clear variant of CSS indigo — about 53 units away from #4B0082. Designers reach for violet 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.
