#18186B sits at 240° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 63% saturation and 26% lightness, it reads as a moderately saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 24, 24, 107 produces a 15.20:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #18186B is a clear variant of CSS navy — about 40 units away from #000080. Designers reach for blue 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.
