Juan del Castillo occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature reads distinctly warm: the reds and earth tones from Juan del Castillo carry the compositional weight. All colours lean toward grey, building depth through value rather than colour punch. #211E1D at 29.3% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The most saturated colour, #AB5234, is reserved to 2.4% of the surface, where it acts as a focal punctuation. The value range spans 57 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This is palette 2 of Juan del Castillo's sequence - a single chapter in a chromatic story told across many works.
