#3F022B sits at 320° on the color wheel, placing it in the rose family of the neutral half of the spectrum. With 94% saturation and 13% lightness, it reads as a fully saturated, deep tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 63, 2, 43 produces a 16.73:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #3F022B is a distant relative of CSS black — about 76 units away from #000000. Designers reach for rose hues at this saturation when the brief calls for bold, immediate signal, and at this lightness when they want weight, depth, and grounded contrast. On screen the balanced cast tends to pair best with either warm or cool accents depending on the surrounding palette.
