For players who are disturbed by the very red character select screen, unzip and drop the below file into your custom UI folder to reduce the red tint. It's a very simple filter added over the window, with just a little bit of green to offset the red. When and if the game developers change the art, you can simply delete the file which will go back to using the default.
If you want to play around with tint (BackgroundColor) and opacity (BackgroundOpacity) of the filter, you can find the values on line 507.
