#0C5A8B sits at 203° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 84% saturation and 30% lightness, it reads as a richly saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 12, 90, 139 produces a 7.37:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #0C5A8B is a clear variant of CSS teal — about 41 units away from #008080. Designers reach for azure hues at this saturation when the brief calls for bold, immediate signal, and at this lightness when they want a present, comfortable mid-canvas voice. On screen the cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
