Alternatively, we could use the player color and its inverse. For now I've just gone with background color and its inverse, since it produced much more normal colors (black and white for most skins). For those who are interested and want to take a look at this code I pushed it to Launchpad at lp:~mixxxdevelopers/mixxx/features_waveform. It's a branch off of features_looping.
