I'm trying to edit the color of the GUI menus, specifically the inventory, to make it a different color. What file would this be under? I went into a resource pack I already have, and I found the generic_54.png file under the directory of:
C:\Users\[me]\AppData\Roaming\.minecraft\resourcepacks\[resourcepack]\assets\minecraft\textures\gui
It looks like the most likely file, but I just want to make sure. If so, I could just change the colors on it, right?
As of 1.8, in un-modded and un-textured minecraft, there is no block that fits your requirements. Probably the closest you'd come is a Snow Block, a Wool Block, a Quartz Block, or, as you said, an Iron Block. The Quartz is extremely close to pure white, closer than the iron block. However, you should look into downloading a texture or a mod that may include a purely white block if none of these are close enough.
Here are the few steps to archive this :
Open Minecraft's data directory. If you don't know how to do this, this screenshot will help you.
Go to versions/The version you use
Open it with WinRar (or any JAR viewer)
Navigate to assets/minecraft/textures/gui
Open icons.png with an image editor. At this point you should see this:
Paint them with red brush.
That's all! Save it and restart MC.

I believe what you are looking for is this directory:
This image file also contains status effect icons, and their backgrounds.
generic_54.png refers to chests, for the most part.
