#123B79 sits at 216° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 74% saturation and 27% lightness, it reads as a richly saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 18, 59, 121 produces a 10.90:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #123B79 is a distant relative of CSS navy — about 62 units away from #000080. Designers reach for azure 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.
