#E0103D sits at 347° on the color wheel, placing it in the red family of the warm half of the spectrum. With 87% saturation and 47% lightness, it reads as a fully saturated, balanced tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 224, 16, 61 produces a 4.87:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #E0103D is essentially indistinguishable from CSS crimson at this fidelity — about 6 units away from #DC143C. Designers reach for red 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 warm cast tends to pair best with cool neutrals around 210°-230° to balance temperature.
