These are not controllable color. This means to turn them on and off with an arduino you will need a relay. Basically, you'll use an external power supply and you run the hot through the relay. The type of relay you want to use will depend really on one thing considering the power draw will be rather low for this many LEDs.

Standard Relay: This will be a cheap physical relay that are used for tons of projects and provide you a simple on off function and they work for 12v or 120v.

Solid State Relay: This is the type you would want to use if you need to dim the lights as they can be turned on/off many more times a second without physical wear. This is necessary to dim LEDs as they will use Pulse Width Management.

EDIT: Red and Blue colors work pretty well for this application. The only thing better is a full white spectrum but LEDs are not capable of that. White LEDs are actually blue with phosphorus painted on them and do not give out the same spectrum as filament bulbs. The accuracy of the wavelengths listed on the product may or may not be as advertised but will probably be close.
