Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

Resistors used: Red - 82 ohm, Green - 56 ohm, Blue - 56 ohm. Allowing approximately 20 mA to flow through LED. Cathode (-) pins of RGB are connected to 8-bit PWM pins of Arduino for voltage control.
