icon as a style is partly defined by its colour: this palette makes that definition concrete. icon occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Mid-saturation across the board: the palette has colour character without chromatic excess. At 2.0%, #D03A27 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 62 units: broad enough to build convincing three-dimensional form. Applied to contemporary work, these proportions immediately evoke the icon register.
