Is it possible to tweek the background colors of the new PRV sharp/flat notes.
The current colors are a little subtle for me. I would like to make them less subtle.
 
Edit:
I figured this one out. I started with the tungston theme and edited it with the Theme editor to increase the color saturation on the sharps and flats.
 then saved it to a new theme.
 

I would think they should be editable within Sonar Preferences Colors as well but haven't verified that.

They are not visible in the preferences>color>prv. That's why I downloaded the Theme Editor. I had not needed it before.
 
:-)

If not then maybe a feature request to add them as they really should be there.
