You can, and many plugins already do. Though it works in insert mode
(like CTRL-X CTRL-S). The documentation has a full example. It's at:

:h complete-functions

You can use inputlist(), but probably not with colours.

:h inputlist()

Check out ":h function-list", too, maybe there's something more to your
liking.

Best,
