#1C77B0 sits at 203° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 73% saturation and 40% 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 28, 119, 176 produces a 4.87:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #1C77B0 is a clear variant of CSS steel blue — about 44 units away from #4682B4. 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.
