#81B7ED sits at 210° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 75% saturation and 72% lightness, it reads as a richly saturated, light tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 129, 183, 237 produces a 9.93:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #81B7ED is a close cousin of CSS sky blue — about 24 units away from #87CEEB. Designers reach for azure hues at this saturation when the brief calls for bold, immediate signal, and at this lightness when they want lift, air, and gentle emphasis. On screen the cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
