I play without the key labels (Windows, build 5875), and the colors are still inverted (light and dark colors between falling notes and keys)You'll also notice that labels and markers are now overlapping (and when they appear together, the label's color is inverted to increase the contrast).
Shouldn't the colors only be inverted when the labels are displayed?
Anyway I'm confused by the fact that the colors of falling notes and keys don't match. There should at least be an option to undo this inversion.
