Replacing vivid r lights on my cyc with colorsource cyc lights

I currently use vivid r 21 lights to light my cyc from above. I use vivid r 63 lights to light my cyc from the ground. I am thinking about replacing the vivid r 21's with the colorsource cyc lights to light the cyc from above. I want to continue using the vivid r 63's as a ground row. My question is, how closely do the two fixtures match in color? Will I notice much of a difference between the two fictures?
