Shield equip: different colours for inside & out?

I’m wondering what everyone would think about the shield equipment having a different colour (green) when being viewed from the inside (where you can fire through it) and gold on the outside (where bullets/projectiles can’t go through) to make them instantly readable from anywhere at a glance.

When I turn a corner in the map, joining a battle, it would be nice to instantly know if I’m shooting through a shield or of I’m shooting against a shield.

I mean… You could I guess. I find it to be redundant. It’s fairly simply to tell which way you can fire through and which way you can’t.
