Deep Heat sets the weight of the palette in urgency and appetite, and Cold Dark is the swatch that breaks rank: a single indigo that stops the set reading as one note. Cold Dark to Hot White spans 73 points of lightness, so the palette can carry its own hierarchy without reaching for a second one. Saturation averages 83 percent with Heat Red at the top, which is loud enough that the palette will fight anything else on the page.
Cold Dark a near-black indigo, depth, focus, the color of late-night thought.
Deep Heat a deep oxblood or garnet, red aged into authority rather than warning.
Heat Red reads as pure adrenaline: alarm, desire, the color of things that move fast.
Warm Orange a citrus-bright orange: enthusiasm, playfulness, an unmistakable call to attention.
Hot White an electric, high-visibility yellow: caution and euphoria share the same wavelength here.
