Teófilo Castillo Guas distributes its values across the middle register, creating harmony without high contrast. Teófilo Castillo Guas builds on cool foundations: the palette favours the blue-cyan-green arc. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #24383A, is reserved to 6.9% of the surface, where it acts as a focal punctuation. At 58 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 3 sits within the larger chromatic argument that Teófilo Castillo Guas's complete body of work advances.
