#3F0C02 sits at 10° on the color wheel, placing it in the red family of the warm 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, 12, 2 produces a 16.60:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #3F0C02 is a distant relative of CSS black — about 64 units away from #000000. Designers reach for red 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 warm cast tends to pair best with cool neutrals around 210°-230° to balance temperature.
