Heorhiy Narbut is high-key - luminous, open, and weighted toward light. Heorhiy Narbut builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 52.6%, #EFF3E2 functions less as a colour accent and more as a complete atmospheric environment. #8A8857 functions as the palette's exclamation mark: highest chroma, lowest percentage (5.4%). A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 3 of Heorhiy Narbut's sequence - a single chapter in a chromatic story told across many works.
