#1BB2F8 sits at 199° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 94% saturation and 54% lightness, it reads as a fully saturated, balanced tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 27, 178, 248 produces a 8.77:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #1BB2F8 is a distant relative of CSS turquoise — about 71 units away from #40E0D0. 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.
