  • Blue is a greenish blue only.

I have set the LED brightness to max, but still can't see a correct blue. How can I fix this?!
It should look something like that, or not ?

The material used on the faceplate for the first batch (yours, it would seem) didn't quite let the blue shine through properly. In successive batches we switched to a different material that makes the blue look blue. In the manual we refer to this color as "white/blue" to reflect the fact that it may look different across units.
