That's why I came with the shift register 74hc595. We need only 3 Arduino digital pins to control as many LEDs as you want. All you need a shift register ic. THere is 12 RGB led with 20 effects.

For connecting 5 RGB LEDs to Arduino we need 5x4= 20 PINS usually, by we are going to reduce this PIN usage to 8 by connecting RGB LEDs in parallel and by using a technique called multiplexing.
