From a design conversation with Kai during #8.

What to build

Each personality gains a terminal-legible color; an agent identity derives its favorite color from its components.

Spec: personality "curious" skill="..." color="#d98e48" - one color per personality, stored as hex data.
Legibility is a parse-time constraint, not a hope: colors must sit in the mid-lightness band (OKLab L ~0.6-0.8, chroma above a gray floor) so they read on dark and light terminals alike.
Derivation: a single-personality composition's favorite is that personality's color. A multi-component identity (e.g. a seat whose role spans several personalities) derives its favorite as the OKLab centroid of the component colors, with chroma restored to the components' minimum so N-way blends don't gray out, clamped back into the legible band.
Rendering: truecolor ANSI with nearest-ANSI-256 fallback, only on a TTY with NO_COLOR unset (same rule #8 established). Containers are transparent to ANSI - only the attached terminal or log capture matters, so captured output stays plain.
Surfaces: describe tints personality lines with their color; the seat dispatch table gains an identity line ('your favorite color is #d98e48'); manifest carries the composed favorite.

Initial palette is placeholder pending Kai's taste: curious #d98e48 (amber), grounded #5fa87a (moss), meticulous #7d9fd3 (slate). The full sixteen-personality palette lands with #10.

Shipped in 934dc2c.

Spec: personality nodes take color="#rrggbb" (docs/person-contract.md, Favorite colors section). The three current personalities carry the placeholder palette: curious #d98e48 amber, grounded #5fa87a moss, meticulous #7d9fd3 slate - swap at will, the gate will tell you if a choice is illegible.
Legibility is parse-time: internal/color validates OKLab lightness 0.60-0.80 and chroma >= 0.05, so black/white/gray and near-gray all fail with a message naming the measured value (tested).
Derivation: color.Favorite computes the OKLab centroid with chroma restored to the components' minimum, clamped into the band. Single component = itself; the amber+slate complementary pair stays above the gray floor (tested). Consumed today for the single-personality composed favorite; the multi-component path is ready for seat identities and the dispatch table.
Surfaces: manifest gains "color" (omitted when the personality declares none); describe's header shows 'favorite #d98e48' always and a tinted swatch on a TTY - truecolor when COLORTERM says so, nearest ANSI-256 otherwise, plain hex text when redirected. Containers are transparent to all of this; only the attached terminal matters.
