Hope there's option for manabar invert just like healthbar

Also It will be nice there's configure for phase icon(Interface\TargetingFrame\UI-PhasingIcon) color according to it's phasing reason(for example, Warmode(red)/ shard(normal)/Chromie time(blue))

you mean invert foreground/background color? There is, Plexus > Frame > Extra Bar Indicator Options > Invert Extra Bar Color. It invers the bar as a whole just like health does.

I like the idea of colors what color is "normal"?

Oh there was option for that. Thanks.

normal means default color r,b,g = 1,1,1
I think.

well correction in WoW use 1,1,1 is black . why not maybe green?

I added more colors now.

This is what i meant. Bigger phase icon is plexus and smaller is phase icon weakauras.
When warmode phased icon color changed to red..

r,b,g = 1,1,1 means 255/255/255 I mis-wrote value.

sorry I thought you meant like box indicators color not icon color. Im not sure about changing the icon. is the weak aura online?
