Actually, I just realized that while it looks fine on the Dark Mixxx theme, it looks terrible on all other themes becaues the Red/Blue signal colors have terrible contrast against the black bubble background which happens on e.g. Classic Mixxx. The only default scheme I can think of that should always yield good contrast on any theme is to take the BgColor of the waveform, take its inverse for the bubble/marker color, and then make the text on the bubble the inverse of the inverse (so just the BgColor). This has good contrast, but isn't very interesting color wise.
