Constructivism painters returned to these tonal relationships repeatedly; this palette is their shared chromatic grammar. Constructivism is strongly light-biased - shadow is suggested rather than declared. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 25.9%, #E9E4D4 functions less as a colour accent and more as a complete atmospheric environment. #784326 functions as the palette's exclamation mark: highest chroma, lowest percentage (7.2%). At 66 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is the light that Constructivism painters chose to live inside.
