So you search for the whole expression, but colorize only the subexpression pointed to by the index. See how the code corresponds to the first two lines? https://dataswamp.org/~incal/figures/emacs/high-low.png If you don't have any subexpression, just a single expression that might be as plain as a word, you don't need an index, instead use (word . face) - I think I mentioned this...? Nevermind. Anyway here is an example of that: https://dataswamp.org/~incal/figures/emacs/dressed-up-as-themselves.png Look at the code and think.
