When playing 2.5 the depressing brown earth really put me off, so I fired up my photoshop and edited few texture files in order to make ground greener. I cannot claim any credits other then changing color. It was for my own use, but feel free to use it yourself if you want to.
It DOES NOT works with 2.4.
Just drop this into you floris mod textures and replace files when asked.
*I made gras textures more natural
*Ground textures a bit less green now
If after installing this your computer will grow arms, murder you and start machine rebellion against humanity, dont blame me, you are doing this on your own.
