Edouard Riou distributes its values across the middle register, creating harmony without high contrast. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #D3D1B7, is reserved to 7.4% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 63 units of the value scale - a span that creates natural depth. In the context of Edouard Riou's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
