Gryef is built on dark foundations, with values clustered toward shadow. Gryef orchestrates warmth above all else - reds, ambers, and siennas take the lead. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. At 30.0%, #14100D functions less as a colour accent and more as a complete atmospheric environment. The most saturated colour, #8A6743, is reserved to 2.0% of the surface, where it acts as a focal punctuation. 82 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This tonal restraint is characteristic of the Gryef approach: colour serves light, not the reverse. This is palette 4 of Gryef's sequence - a single chapter in a chromatic story told across many works.
