Mid-key values give Eugene Boudin its characteristic quietness - nothing blazes, nothing disappears. Eugene Boudin builds on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 6.8% is devoted to #866737, yet that small allocation delivers the palette's entire chromatic tension. The value range of 54 units sits in the comfortable middle: enough depth, enough light, neither extreme. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Eugene Boudin's full range of palettes, group 15 represents one movement in an ongoing chromatic dialogue.
