The advertisement tradition carries a consistent chromatic signature, and this master palette captures its essence. Mid-key values give advertisement its characteristic quietness - nothing blazes, nothing disappears. 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. The saturated accent, #D87434, registers at 4.0% - sparse enough to feel like a deliberate surprise. 65 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Applied to contemporary work, these proportions immediately evoke the advertisement register.
