SL-101 / Colour as Effect
The Selective World
One object keeps its colour — redeemed only by a point of view that justifies it.
The brief
One object holding its colour while the world desaturates, with a reason — memory, obsession, what the character actually sees — and the selection following a substance rather than a mask edge.
Why it's hard
You get a hard rotoscoped edge with grey bleeding onto the hands, and the desaturation stays on in the objective wide, which kills the justification.
Selective colour without a point of view is decoration. Show the full-colour wide first so the selection has something to measure against.

Starter prompt
Built with the CEMI MediaMax system for Google Veo 3.1. Prompts stay in English — that is the language these models take instructions in. Treat it as a starting point and start varying it.
An indigo dyer lifts a skein from a fermentation vat in a courtyard dye house, in the style of Zhang Yimou with Zhao Xiaoding's colour-structured cinematography. POV RULE that justifies the grade: the world holds its full colour in the wide, but in her looking-frames — the close reverse down her sightline into the vat — everything desaturates to bone and slate EXCEPT the specific vat blue she has been chasing all day, which keeps full chroma on the yarn, on her forearms, and in the drip trail on the flagstones. The selection follows the dye, not a mask edge. Dirty foreground: a dripping bamboo pole and a hank of undyed cotton across the lower frame; 50mm at f/2, warm halation, focus breathing on the pull. Operator kneels at vat height with a small unsteady settle. Materials: crusted vat rim, wet linen, oxidising blue turning green in air.

Selective colour needs a point of view or it is decoration — here the rule is that only her looking-frames desaturate, so the audience reads obsession rather than a filter. Tying the surviving colour to a substance (the dye itself, including the drips) keeps it physical instead of a cut-out mask. Show the full-colour wide first so the selection has something to be measured against.
