You would have RGB Mixing.
Another thing that is sort of neat that I do often that's sort of a "colorchanger/LED cop-out" is gel three instruments with R27, R80, R61 (the primary red, green, and blue) and focus them in the same spot while hanging them as close as possible next to each other. Often I find we have just enough of an inventory to do that. Now, this is with S4 ERSes because they burn almost white so you can pretty much have any color and for me it's cheaper than buying scrollers, renting them, plus we dont have readily available DMX on stage. I wouldn't be so quick to do this with PARs of any kind (regular or S4) just because pars diffuse so much and you wouldn't be garanteed to get the same focus on all three units.
This has the small advantage over most scrollers just because if the director (like some I've worked with) are like "i want more of ____ color!" then you can give it to them in a way that makes since. Now, LED lights are doing the same thing, but this is a good alternative.
Just one note: Watch those shadows because they can get a little funky at times. But with some planning this is a really fun technique.
it would but then you would loose control of the leds, assuming your not going to buy a larger board which could do both at once.

These were pretty standard a number of years ago, typically they had the option of several control systems depending on what you were set up with, if you look at the connector feeding the dimmer assuming it is not directly wired in for control, if you have 4 pin xlr or a funny odd smaller connector, it is AMX if it is 5 pin xlr then typically it is dmx, also look at the output from your console.
It is possible that you have a converter in the system to change your control protocol. It typically takes some looking around seeing how they are connected and what is there to figure it all out. Usually on a pro installation the stuff is pretty much labeled.
It is probably possible to find the final input, un terminate it and get the dmx out assuming it is dmx, since most of the racks were all set up to be able to add additional racks to the system.
Does it look like this?

In a rack install like that, there usually is no jack on the rack, or near the rack, for a through. However, there is a terminal block inside the rack that you can tie into to get a DMX through rather easily. If you dig in your book a bit, I am sure you can find it. If you do not feel comfortable doing it give you local lighting company a call and they can get it put in for you. It will save you a pretty penny, so I would do some reading!
