Cool Red Palette hides blue inside red rather than placing the two hues side by side. Black Cherry and Blue Merlot gain depth without the brown cast that often warms dark reds, while Berry Signal and Cool Ruby tighten the middle around a berry undertone.
CSS Crimson provides a standardized reference point before Frosted Rose lifts the sequence. Every swatch remains recognizably red; the cooling effect comes from resisting orange and yellow, not from crossing fully into purple.
Use the darkest pair for broad fields or high-contrast type, the middle shades for active states and editorial emphasis, and the light endpoint for secondary surfaces. This is a red system with internal temperature control, not a blue-to-red gradient.
