Glenn Cooper Henshaw sits in the centre of the value range, lending the palette a sense of even, sustained light. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #423528 delivers the chromatic peak at only 7.7% - a small shot of colour with outsized visual impact. Spanning 28 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Glenn Cooper Henshaw's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
