Color changing led light for a lamp help?!

I’m building a trippy lamp and want a color changing led light mounted on the inside on the bottom. (It’s going to be a shadow lamp).

I’m getting lost in videos of soldering led light chips and wires that I have no clue where to start looking to buy.

Is there an easy way to buy/build just a USB powered color changing light chip/diode/mount/housing?

Something as powerful as say a color changing Salt Lamp or a couple dots worth of a strip light.

Any help/suggestions/links welcome and appreciated.

Couldn’t find a color changing light bulb small enough. The base dimensions would be 3.5" x 3.5"
