What color bulbs to run is kind of an if/then situation. For example, back in the day, when metal halides were king, most folks ran a near daylight halide, with actinic fluorescent bulbs to give fish and corals more pop. Now, with LEDs, you can adjust them to any spectrum, so you may choose T5s that complement whatever you have decided on. It's up to you!
