Sb2 : UI : minor : Conflict in colour choices

The background colour override that has been selected for the Notes pane in the full screen Inspector HUD currently conflicts with the system highlight preference, “Silver,” in that it is nearly the same tone and cannot be seen (maybe a 1% difference). Can you override the highlight colour in that widget – make it a darker grey or something universal? Also, while the “Graphite” choice can be seen, it is also quite low in contrast and a little difficult to see, especially when the focus has been removed from the HUD. I wouldn’t bring it up, except that this are common system preferences.
