The plants themselves will stay whatever color they were. They are perennials.
The only part of the plant which will produce other colors will be the seeds,
but the Echinacea purpurea PLANT will stay the same. I've not heard of red,
where did you get red Echniacea? Oh, unless, of course, common names...and all.

I have a large established bed of purple cone flowers. I recently
purchased some red and some white cone flowers also. I was told that
these colors come from hybrid plants, so my question is: Will they
cross polinate or will they retain their true colors? Anyone have any
experience with this?
