cool newbie experiment !
I've done those two with custom gradients, works fine.
Not precisely calibrated, but quite ok, I'd say.
Same example as above, for ease of reference.
Find them here:

my Photoshop gradient file is included for you to tweak, don't know if other programs can read this though.
Now if anybody could explain how to customize the RMS displays in the mixer's master channel in the same way, please ?
Have done a quick search and found no related png's ...
cheers,
Rhino
edit: updated the zip with the rms png.
