You control the color by choosing the image that is displayed. You can also set the digital frame to random cycle for an ever changing display. I liked strong geometric images or blurry ambient images. Somehow, "regular" images didn't work as well for me.
The patterns, layer-spacing and the thickness of the paper cutouts really affect the look of the moodlight. The cutouts shown here are made from discarded failures from other projects.
Theoretically (I did not accomplish this) you could hack the frame's IR remote with an Arduino or Raspberry Pi to create an "ambilight" or other sensing/smart or IOT display.
I also tried acrylic and plastic cutouts etc. They were very eye catching, but they reminded me of 70's sci-fi movie sets. Cool for certain events, but not what I was after.
If I can find those pics, or recreate them, I will post pics of these also.
