Palettes — Index

A palette is the deck's color behavior — proportion, role, temperament. It does not supply HEX values; those come from design_spec.colors. The palette tells the model how to use the HEX values: which dominates, which carries accent, what proportion the background occupies, what the overall temperament feels like.

Why this split: SVG renders the HEX precisely from design_spec. The AI image must use the same HEX values so the image visually belongs in the deck — but the image needs more than a HEX list; it needs a usage rule. That's the palette.

2. Escape hatch — custom

When no preset temperament matches (brand HEX outside preset ranges, ceremonial / cultural / niche aesthetic), set image_palette: custom and supply a one-paragraph image_palette_behavior.

Trigger — all of:

Condition	Check against
No preset temperament fits	design_spec.e Color Scheme
Brand / template / chat names no preset	truth-precedence inputs
Not expressible as "preset X + small HEX swap"	Strategist confirmation chat

Hard rule — palette_behavior prose:

Rule	Value
Length	One paragraph, 2-5 sentences
Per-HEX content	role + approximate area share (proportion follows information weight; no fixed % menu)
HEX source	Quote design_spec.colors values verbatim with backticks; never invent HEX
Forbidden	Naming a competing preset ("like macaron but darker")

- image_palette: custom
- image_palette_behavior: "Primary deep aubergine `#4C1D95` anchors the dominant ~35% of canvas; secondary warm cream `#FEF3C7` carries ~55% as breathing field; accent burnished gold `#D4AF37` appears only in 5-10% as small ceremonial accents. Restrained, ceremonial gravitas — no fourth color."

Note: §4's rendering × palette matrix only covers the 14 presets. When palette: custom, Strategist owns the compatibility judgment in h.5.

Hard rule: custom is a tail-case, not a default. See strategist.md h.5 for the one-custom-per-dimension limit.

5. How to use

1. After picking rendering, look up your candidate palette in the auto-selection table.
2. Cross-check the compatibility matrix — if ✗, pick the alternate.
3. read_file image-palettes/<chosen>.md and apply its proportion + role rules to the deck's HEX values when assembling prompts. (For custom, this step is replaced by the consumption branch in image-generator.md Step 2 — no preset file to read.)

Lock for the whole deck.
