A couple of weeks ago I bought an Xpin White DMD display. I also bought a Stern blue DMD cover. The White Xpin has a grey colour gel that tones down the white a bit and overall the white looks really nice (definitely different).
I then put the grey colour gel on the blue cover and installed it in the machine. Overall it looks awesome, it's a really nice shade of blue. Not too dark, not too bright, overall it's just right and very pleasing to the eye. Below are a couple of still pictures and a short vid (my 10 year old was pretty excited to complete CLU!). The camera makes the DMD look a little blue / whitish but it's definitely an all out nice shade of blue when you are looking at in in person.
The cool thing about the white display is that you can change it up and use a bunch of different colours if you want (you just peel off the colour gel and install it over the display). My son wants to go with purple next!
