#88B5F9 sits at 216° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 90% saturation and 75% lightness, it reads as a fully saturated, very light tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 136, 181, 249 produces a 10.02:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #88B5F9 is a clear variant of CSS sky blue — about 29 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.
