We define colors in noninteractive shells for historical reasons (because colors used to be universal variables). The other potential reason is to get regular syntax highlighting for commands like: fish -c 'read --shell' but if anyone actually uses that they can probably load a theme explicitly. Stop defining colors in noninteractive shells. It's usually not a good idea to make them behave differently from interactive ones, but color seems only relevant for interactive shells? Let's see if anyone complains.. we may end up reverting this if people want to use noninteractive fish to query colors.. but I'm not sure why that would be necessary. Closes #12673
