#31316F sits at 240° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 39% saturation and 31% lightness, it reads as a softly muted, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 49, 49, 111 produces a 11.67:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #31316F is a clear variant of CSS indigo — about 59 units away from #4B0082. 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.
