Toyota Hokkei is high-key - luminous, open, and weighted toward light. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 1.5%, #B14341 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 65 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Palette 4 sits within the larger chromatic argument that Toyota Hokkei's complete body of work advances.
