# Looks

`look` picks a finish (gradient, glow, glass, tint, outline, ring, brand); every colour is a theme token or a per-instance colour input (`color`, `from`, `to`, `ink`, `accent`, `tile`, `tileInk`). `startTile` puts a brand tile at the start edge. Separate hosts - XWUIButton clears its container on render. Reference: docs/REF_BUTTON_PRESETS.md.
