This is a pretty simple GUI recolour. I made a blue pack which can be found here, someone requested a red version so I made it. There should be more info in the file found inside the .zip called "readme.txt".
A blue version of this pack can be found here.
How I made the pack:
Making this pack was pretty simple; Photoshop made it pretty easy, here is what I did.
1. Get the vanilla GUIs.
2. Add a colour layer (HEX: ff0000) above the GUI and mask it.
3. Use the blend mode 'multiply' to colour the GUI easily.
