Where are you coloring players? In the PokerStars software or via the PokerTracker 4 note window? If it's in PokerStars then the HUD is overlayed on the PokerStars window so no that wouldn't be possible.

Please note that you do not have to click on the small color square itself in PokerStars - anywhere on the line will do if a part of it is not underneath the HUD. If the colors are obscured by the HUD so you do not know if you are on the correct line then you can increase the transparency of your HUD background. Alternatively you can adjust the positioning of your HUD and/or the size of your HUD profile and/or hide the HUD temporarily via the PT-icon and/or use the 'Notes' tab in the PokerStars chat window to assign colors.
