P: Folder Highlighter in LR

I am having great difficulty seeing the folder highlighter when moving images/folders because it is very pale grey and it is particularly difficult if there is some light in the room.  I understand that there are no settings in LR for changing the interface look, colour or contrast.  It would be extremely helpful if this could be changed so that I can use a different colour or just put a simple stroke border around the current highlighter so that I am confident that my images have gone to the correct location. Thank you.    Dave Hull
