MinimalLib - the current interface in MinimalLib doesn't expose the options needed to do multi-color highlighting.

Is your feature request related to a problem? Please describe.
Minimal lib currently doesn't support multicolor substruct matches.

Describe the solution you'd like
Unsure of the implementation but either an option to have a color per bond and atom like in the getting started of RDKit https://www.rdkit.org/docs/GettingStartedInPython.html.

OR

An option to do color matching per structure match in SMILES/SMARTS strings containing dot notation.

OR

An option to map substructure match with their desired colour.

Describe alternatives you've considered
Server-side rendering with main RDKit, it'd be simple to have that in the MinimalLib for heavy users of RDKit.js or other distribution of the minimallib.

Additional context
None.
