hello...I want to change the color of the bar that displays at the bottom of your email screens. At the main email window, there is a bar at the bottom with an envelope and a + at the left side. Once you go into an email account, you have a white bar at the bottom with refresh and + at the left.

What is the name of those 2 png's and their location? I have the black scrim on my email and I want to change the color.
