Unless you have fixtures that you can spare, concentrate your color changers on the floor. Color fill is the foundation for intelligent and high tech effects. If used properly, you can wash the dancefloor with light and let your intels and other effects move around and add some changeup.
The word is getting out ..... how will I ever compete? Aim 'em at the dance floor and if you've got a couple spares, aim them at the wall behind you in contrasting colors. For what they cost these days, its a small investment.
Check in with Bill from ESC...... he had a special going with the new Chauvet Omega 250C's......I bought four sight unseen and they've been great so far and my monetary investment was far less than the cost of a single Martin MX4 scanner.
