This is super interesting to me, as I have been thinking of getting a couple of smart light bulbs. Using the app, you can change the bulb into 16 million different colors (or so they claim).
You can select different shades of white such as cool, warm, cold etc, or any color you choose using their app that has a color wheel on it.

I was thinking I would enjoy sitting in violet light, but never thought of bright orange/yellow to simulate a bright sun in the sky.

I'm constantly on the lookout for the magic cure for my depression and mood swings.

I've managed to find myself in the sad capital of the galaxy also, my area averages six feet of rain a year. I go months without seeing the sun or moon.
