#4159F9 sits at 232° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 94% saturation and 62% lightness, it reads as a fully saturated, light tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 65, 89, 249 produces a 5.22:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #4159F9 is a clear variant of CSS royal blue — about 29 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.
