Spectrum Red
#e31f26
Spectrum Red is the purest, most saturated red in this group, with a chroma reading that dominates its Lab values and very little to soften it. It looks like a pillar box or a fresh tomato. Wada sets it against Orange Yellow for a fiery warm pair, Blue for a primary-color directness, and Aconite Violet for something more unexpected. White text on it reaches 4.7:1, just enough for normal-size text, while black on it sits at 4.5:1, right at the edge. Use it sparingly in signage, flags, lacquered furniture or a poster headline.
