Francisco Barrera occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Yellow, ochre, sienna: warm hues that Francisco Barrera deploys as the palette's primary energy. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #CC9A40, is reserved to 0.9% of the surface, where it acts as a focal punctuation. The full value range is 64 units: broad enough to build convincing three-dimensional form. This is palette 2 of Francisco Barrera's sequence - a single chapter in a chromatic story told across many works.
