#0B187D sits at 233° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 84% saturation and 27% lightness, it reads as a richly saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 11, 24, 125 produces a 14.57:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #0B187D is a clear variant of CSS navy — about 27 units away from #000080. Designers reach for blue 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.
