#B2DEF9 sits at 203° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 86% saturation and 84% lightness, it reads as a fully saturated, very light tone — a soft but unmistakably tinted presence. Its RGB mix of 178, 222, 249 produces a 14.71:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #B2DEF9 is a clear variant of CSS sky blue — about 48 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.
