#2243CB sits at 228° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 71% saturation and 46% lightness, it reads as a richly saturated, balanced tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 34, 67, 203 produces a 7.68:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #2243CB is a clear variant of CSS royal blue — about 54 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.
