#1F12BA sits at 245° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 82% saturation and 40% lightness, it reads as a richly saturated, shadowed tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 31, 18, 186 produces a 11.33:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #1F12BA is a distant relative of CSS navy — about 68 units away from #000080. Designers reach for blue hues at this saturation when the brief calls for bold, immediate signal, 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.
