It sounds like you want some sort of syntax highlighting. It
allows for changing not only the color but the attributes
(bold/italic/underline/undercurl) assuming your display supports
it (gvim does, and some characteristics may be on the terminal
such as bold).
Assuming you have some way to discern your italic text, you can
do things like
:hi Italic gui=italic
:match Italic !/\w*\(/\w\+\)*/!
which will highlight text like /this/ or /compound/strings/ as
italicized.
You can read more at
:help :hi
:help :match
:help :syn-match
and it can be helpful to read some of the syntax-highlighting
files that come with vim in your $VIMRUNTIME/syntax/ especially
for things that do something similar to what you describe.
Particularly, the rst.vim file may have a lot of good stuff in it.
