Drums UI, color of bags

[sas0969]

I've been really struggling with having the items in my bags be so dark in a such a very dark background of the bags. I've tried to figure out how to change just the bag color. (I added the skin change, only to realize that didn't change the bags).
If someone could point me to an add-on, tell me how to fix it, or make a fix (if it's easy enough)?
I added a picture of just how dark they look for me.

Thanks in advance for any help.
