#64C0EA sits at 199° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 76% saturation and 65% 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 100, 192, 234 produces a 10.27:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #64C0EA is a clear variant of CSS sky blue — about 38 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 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.
