Aren't these 3 lead LEDs? If so, series connections are out. Are they CA or CC LEDs? The values you gave seem overdriven to me and I would worry about their longevity. I can't think of a single chip that would work with your specific requirement for 30 Dual color LEDs. You would probably need small value balancing resistors and would be best served by setting max current and PWMing for brightness. By any chance, were you able to find a data sheet for that LED?
