Julius Caesar Ibbetson is strongly light-biased - shadow is suggested rather than declared. Julius Caesar Ibbetson builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #A17F3C, registers at 1.9% - sparse enough to feel like a deliberate surprise. At 66 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 1 of Julius Caesar Ibbetson's sequence - a single chapter in a chromatic story told across many works.
