Purple snow in skyrim, what is causing this?

I just started a new Skyrim game and I noticed that the colour/texture of snowy rocks seemed off. It is a bright bluey purple colour that really ruins the immersion of the game for me.

I deactivated all mods and expansions and deleted my skyrim folder and redownloaded it from steam.

Same problem.

Can I try anything else? Or am I colour blind / monitor issue?

Solution 1:

OK, so I thought I was looking at snow. I was actually looking at a rock texture. A broken rock texture. When I told steam to delete skyrim and redownload it again it didn't wipe out a texture folder.

In my SteamLibrary\steamapps\common\Skyrim\Data folder there was a suspicious folder named "textures" I deleted it and now it works! Must have been a remnant of an old mod.
