Quoted from wxforecaster:in the rare blue color that was only used on a few games (Tron LE, Avatar LE?), but I think would look awesome on quite a few other titles.
To my knowledge, Stern never released a game with a blue DMD. They have always been an after-market add-on.
Blue DMDs look cool in photos but many people have trouble focusing on blue LED light and find them uncomfortable to look at. Prescription glasses often include blue blockers to reduce eyestrain. YMMV.
