#1535D5 sits at 230° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 82% saturation and 46% lightness, it reads as a richly saturated, balanced tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 21, 53, 213 produces a 8.39:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #1535D5 is a distant relative of CSS royal blue — about 69 units away from #4169E1. Designers reach for blue 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.
