#25A4F4 sits at 203° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 90% saturation and 55% lightness, it reads as a fully saturated, light tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 37, 164, 244 produces a 7.70:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #25A4F4 is a distant relative of CSS royal blue — about 68 units away from #4169E1. 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.
