LED brightness and colors

[Meads]

I just got an S3 and first thing I noticed was the LEDs that were WAY too bright in a dimly lit control room.
Luckily this is adjustable from utility mode. But when I use the global brightness setting to turn the LEDs down (27 seems to be a value that works for me) the track colors get screwed. Tracks that are actually green appear blue on the surface. I didn't touch any of the other settings.
Is there a way to dim the brightness without affecting the hue? Also is there a manual for the utility mode? It's not necessarily self explanatory what those settings are supposed to do exactly, especially in the LED section.

Also - it would be nice if the brightness setting would be accessible from EUControl. LED brightness for Dock and Artist Control can be set there. Why not the same love for the S3?
