Colour names the family, never the rank. Under the [five-colour family key](https://blockspace.wiki/glossary/five-colour-family-key/), Ordinal Sats, Runes, BRC-20, Alkanes and Omni, the five families with the most blockspace, each carry a colour; every other family is the grey Other. A family keeps its colour on every page and in every mode, and a filter never repaints what remains.
