Re: Game is orange and blue

@nightbattalion  Do you have ReShade or GShade installed?  If so, please remove it and repair the game again.

If that doesn't help, please try playing in a clean user folder.  Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.)  Don't add anything to the new folder yet; just have a look around.

If the colors are still off, please run a dxdiag and attach it to a post.
