#159FD1 sits at 196° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 82% saturation and 45% lightness, it reads as a richly saturated, balanced tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 21, 159, 209 produces a 6.91:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #159FD1 is a distant relative of CSS steel blue — about 64 units away from #4682B4. 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.
