Question about Gardenspot LED's

Id like to know if anyone knows how to do this. I have 4 sections of my yard running the Sylvania RGB Gardenspot lights.

Id like to have each one be a different color when I press a button. I cant find a smart app that can do this. There only seem to be ones that can set all of them to the same color or custom ones that make them all random. Is there an app out there that can custom direct the lights on button press? I cant seem to find it. Again I want on, off, and color. Each one being different and can still be grouped into a single button press.

Example I want Red, White, and Blue for memorial day.

What @anon36505037 said. Except I don’t think you’ll get true white with those like you’re example you mentioned.

Pure white isnt an issue for me.
