#223A9E sits at 228° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 65% saturation and 38% lightness, it reads as a richly saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 34, 58, 158 produces a 9.69:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #223A9E is a distant relative of CSS navy — about 74 units away from #000080. Designers reach for blue hues at this saturation when the brief calls for a conversational, mid-energy register, 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.
