#3B3B9E sits at 240° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 46% saturation and 43% lightness, it reads as a moderately saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 59, 59, 158 produces a 9.11:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #3B3B9E is a distant relative of CSS indigo — about 67 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.
