How to create a texture?

I can create a new material, and use Unity’s textures to create a different looking textured material, but how can I make a new texture itself?

Use Photoshop or Gimp or whatever.

Take a look at the asset importing section of the Unity3d website. That will tell you file types unity supports and what is imported with the file type (like textures won’t be imported from .obj files).

And also you can use Sumo Paint.
Its free and power full.

No need to install third party apps, make a screenshot and drag it into Unity… :O)
