Default UI bg color (for hp, hunger, etc)

I'm curious what the rgba for the default background ui is. Adding a new elements to the ui and I would like them matching if possible.

(also if anyone knows what texture the progress bar is, lemmi know that too! thx)

edit:
its probably just a specific texture, so if someone can shoot me that, would be greatly appreciated!

 

assets/icons/greyout.mat is the material used there I believe

 

there is also a color associated, however im unsure on what it is. happen to know that too?

its getting close but not quite there yet

 

#fff with abit of transparency
