Values in poster tilt decisively toward white, giving the palette its luminous character. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. #6C4929 delivers the chromatic peak at only 7.0% - a small shot of colour with outsized visual impact. A value spread of 63 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
