Values in Sidney Richard Percy tilt decisively toward white, giving the palette its luminous character. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. At 32.1%, #FFFFFF functions less as a colour accent and more as a complete atmospheric environment. #D2B885 delivers the chromatic peak at only 8.6% - a small shot of colour with outsized visual impact. A value spread of 73 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. This is palette 3 of Sidney Richard Percy's sequence - a single chapter in a chromatic story told across many works.
