#143D5F sits at 207° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 65% saturation and 23% lightness, it reads as a richly saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 20, 61, 95 produces a 11.28:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #143D5F is a distant relative of CSS navy — about 72 units away from #000080. Designers reach for azure 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.
