The colour changing LED projects against a white cut out of the Aurora against a black background. There are small holes in the background with a white LED in behind to give the appearance of stars. When I was looking at images of the Aurora Borealis on Google a lot of them had trees in the foreground so I added some silhouettes of trees to make it look more authentic.
