Values in Theodor Groll tilt decisively toward white, giving the palette its luminous character. Theodor Groll builds on cool foundations: the palette favours the blue-cyan-green arc. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #715D3E, registers at 8.6% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 57 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 1 of Theodor Groll's sequence - a single chapter in a chromatic story told across many works.
