Gustave Caillebotte distributes its values across the middle register, creating harmony without high contrast. Yellow, ochre, sienna: warm hues that Gustave Caillebotte deploys as the palette's primary energy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #A07E43 delivers the chromatic peak at only 7.2% - a small shot of colour with outsized visual impact. The full value range is 60 units: broad enough to build convincing three-dimensional form. In the context of Gustave Caillebotte's full range of palettes, group 13 represents one movement in an ongoing chromatic dialogue.
