How do you change the colors and light show effects? Does it come with a remote control or an app you can control with your phone?

Hi Deanna, The changing of the colors is done by simply turning the power on and off to the light, normally the pool light is tied to a light switch so it is just a matter of flipping the light switch on and off to cycle to the next color or color show. There is not an app available at this time to control the bulb through a phone.
