#242D53 sits at 229° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 39% saturation and 23% lightness, it reads as a softly muted, deep tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 36, 45, 83 produces a 13.33:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #242D53 is a distant relative of CSS navy — about 73 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 weight, depth, and grounded contrast. On screen the cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
