How the ECMA-48, #AIXTerm, and ITU T.416 indexed colours come out is up to the #terminal; as is, indeed, how the default colour comes out.

For these indexed colour schemes there's usually a palette that maps to RGB. Some terminal _emulators_ can adjust the palette. But real terminals didn't even have the 256-colour indexed system, let alone palettes.

The applications pretty much have no say.

The colour #terminal paradigm just doesn't work that way.

Applications can pick from the 8 colours of ECMA-48, or from that plus the additional 8 colours from IBM #AIXterm, or from the 256 indexed colour set of ITU T.416, or from the full ITU T.416 RGB direct colour system.

There are no "modes" or "themes". An application asks for the default colour, or for an explicit ECMA-48, AIXterm, T.416 indexed colour, or RGB direct colour.
