Values in Boris Grigoriev rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #93682D, registers at 5.1% - sparse enough to feel like a deliberate surprise. The full value range is 65 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 5 of Boris Grigoriev's sequence - a single chapter in a chromatic story told across many works.
