Bink/fade alternate colors in a room (Christmas colors)

I have a 2 rooms(second story) with windows that face the street, each room has 2 color bulbs in center ceiling fixtures. I would like to use them for christmas lighting and flash/ fade the lights different colors, also maybe swapping colors (red and green) between bulbs or rooms or both.

I also have 3 porch lantern lights with color bulbs (3bulbs each) that I would like to do the same affect…its the main reason I wanted color porch lights.
