I have a suggestion to be able to let a current debuff change the frame health background color at the same time, just with another brightness of the actual debuff color, or any pre-defined color.

See this example: https://gyazo.com/95f5499b260a8d4ee5af81fdedaef870 .. this is from a curse.

Whenever there's a debuff out that can be dispelled, the frame background color will always be a darker brightness of the actual debuff color.

Already possible, you can  use the standard health bar indicator or create an extra bar and link the bar  to the health-deficit status + desired debuffs statuses.

Another possibility is tu use a square/rectangle indicator placed behind health bar.

This was really hard and confusing. I don't think I can create what I want to have with my current setup without sacrificing something else.

I want normal health bar to be class colored (inverted colors), with health deflict to be the brighter version of the class color. So far so good.

Now I want the health bar to be bright pink when cursed, and the health deflict to be the inverted dark pink color. While this works, I cannot get the normal bright class color health deflict to overwrite this with frame levels.

I've tried what you suggested, with another extra bar, multibars, another square indicator - everything and I can't get everything to work altogether. It's all about the inverted colors the way I want them to work, which actually messes this up.
