A tag carries a colour, and every place a tag appears shows it — a product card, the filter drawer's control, the admin taxonomy screen — except the removable chips beside the Filters button, which rendered every filter as a default grey. Picking `vintage` from a control that showed it in red produced a grey chip of the same name right next to it.
Only tags get a colour, because only tags have one. Category, price, favorites and status keep the default, and that asymmetry is the point: in a row mixing four kinds of filter, colour now means "this is a tag". Nothing depends on it — every chip still carries its label — so this reads the same to anyone who cannot distinguish the colours.
The close control inherits the tag's text colour, so a coloured chip gets a matching cross rather than a grey one on a coloured ground. A tag not yet in the loaded options has no colour to use and keeps the default, which is the same window the existing `Tag {id}` label fallback covers.
The test asserts the chip's colour equals the same tag's colour on a product card, rather than asserting it is red. The colour is derived from the tag's name and free to change; what must hold is that a tag looks like itself wherever it appears, and comparing the two places says that directly. Confirmed to fail without the change — the old grey chip sets no colour class at all.
Verified visually as well as by assertion: three tags selected together render in the drawer, in the chip row and on the card in the same colours.
