Hello! New here! I want to install color LED in the pool. Currently, there are 2 white light housings in the pool and then a single white light in the spa. I believe they are all Zodiac/Jandy white lights. Question is: do I have to install 2 color lights in the pool? If I replace 1 in the pool will the white light alter the overall color in the pool? Also how easy is this for a DIY person? Any input or recommendations appreciated.
