#1D59B9 sits at 217° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 73% saturation and 42% 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 29, 89, 185 produces a 6.60:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #1D59B9 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.
