The way I was going to control the different colors and mixing programs was with a microcontroller. With a microcontroller you could have set certain output pins (there are 28 in mine and each output pin can be a series of LED's) that control the changing colors (changing voltage) on a set time frame, like a calender.

And why did you choose 10mm LED's? I found 5mm LED's to be pretty much the same brightness, however since 5mm are smaller you could have twice the LED's compared to 10mm. Just wondering. Also are you using drivers for the LED's?
