Vicente López Portaña dwells firmly in the shadows, with no more than a whisper of light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #0D100E claims 41.6% of the surface, functioning as the work's tonal foundation. #A02A11 functions as the palette's exclamation mark: highest chroma, lowest percentage (4.9%). At 50 units across the value scale, the palette keeps contrast readable without letting it dominate. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. Vicente López Portaña's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
