The "Invert Colors" option does not take into account absorb bars or incoming healing bars.

Example

The top bar has "invert colors" selected. It should be dark teal as I am a monk (like the bar at the bottom) but it is instead brown.

This only occurs when incoming absorbs is set to not go outside the bar limit. I think the invert colors option is inverting the color of the absorb bar and applying it to the whole health bar. This also occurs with Incoming healing (and I assume heal absorbs although I didn't test it).
