5.1 Phrase Colours

Can the phrase colours be adjusted anywhere, I can't see any options yet. My initial impression is that the colours are too dominat on the screen and make the waveform area very cluttered looking.

It would be great if the the phrase sections were semi transparent so the colours were not so strong and the waveforms were still visible. Alternatively a lighter shade of each colour might tone the UI down.

I was hoping for some UI improvements after 5.0 made everything more difficult to see but it looks like new functions have taken priority.
