Values in Igor Grabar tilt decisively toward white, giving the palette its luminous character. Igor Grabar 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. At 5.4%, #AF9B71 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 51 units across the value scale, the palette keeps contrast readable without letting it dominate. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 4 of Igor Grabar's sequence - a single chapter in a chromatic story told across many works.
