Change casting bar color?

[theoldnite]

Hey is it possible to change the color of the casting bar?

Reason I want it changed is because the casting bar and auto-attack bar contrast with eachother too much and when im fighting something, only the auto attack bar stands out to me, making me think things are casting super slow and harder to time casts between auto attacks than before. If need be, I may just swap the casting bar back to the original bar, but i like the look of the profit one, just want it to be yellow like the auto attack bar!

Anyone able to help me out here?
