#0B5DEA sits at 218° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 91% saturation and 48% lightness, it reads as a fully saturated, balanced tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 11, 93, 234 produces a 5.57:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #0B5DEA is a clear variant of CSS royal blue — about 56 units away from #4169E1. 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.
