Gustave Caillebotte occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Gustave Caillebotte orchestrates warmth above all else - reds, ambers, and siennas take the lead. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #B4895F delivers the chromatic peak at only 4.6% - a small shot of colour with outsized visual impact. 69 units of value range underpin the palette's structural clarity: the eye always knows where light falls. In the context of Gustave Caillebotte's full range of palettes, group 9 represents one movement in an ongoing chromatic dialogue.
