The proof that Plaza and Chrome are M3E variants: four source colours, three materials, and every cell reads only M3 roles (primary, secc, scl…). Changing the source recolours everything, without a single variant-specific colour token.
Rules
- Schemes are real Material You (TonalSpot) schemes generated with material-color-utilities from the source colour.
- Plaza and Chrome only add tint-free material: gloss-hi, gloss-edge, shade, shadow-plaza, shadow-chrome, and color-mix() blends.
- Always let people choose: light, dark or system mode; theme colour; Material You on Android 12+.
