#04248C sits at 226° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 94% saturation and 28% lightness, it reads as a fully saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 4, 36, 140 produces a 12.83:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #04248C is a clear variant of CSS navy — about 38 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.
