Good to know it works.
What do you mean by stats? The scores? No they don't, they only affect the way the collector is behaves. Blue is slow, red is hard to turn and green is "drunk". I have to do some balancing with those because I think red is by far the least annoying where as green makes it next to impossible. If you mean the bar that you are filling, color's size affects the amount it grows. So you have to consider timing to get the maximum amount.
It could also be a good idea to give more scores when the colors are in good balance. Now you will always end up with the same scores on the same level.
