Quoted from Sprudeldudel:
I personally think it wahses out the contrast on the Playfield. To my opinion the bright whites really set the scene for the other colors. Especially the FORCE-area suffers from being dulled down. More to that on the photo above the pink doesnt match. I'm glad you all like it, tho. That's what is great about pinball - everyone gets to do or not do whatever he or she wants
I wasn't super-sure I'd want the character inserts colored, but once I did it, I wouldn't go back. Also, the Leia one is more purple in real life. It photographs pinkish.
The FORCE bracket is designed to complement the playfield art with the dark to light shades of blue transition. So is the duotone lightsaber duel insert, with blue on the bottom side matching the playfield that transitions to red on the top side that flows into the red lightsaber on the playfield.
Stern LED whites drive me crazy on pinball machines because they're just too bright in a dark room, so the biggest benefit for me is cutting that glare a little with the light filters. Ghostbusters was WAY worse in that regard, but STAR WARS has some of that, too.
