You are not allowed to recolor our texture. The hard work is to create the texture, so if you only recolor the part made by you is really tiny. You can recolor our texture only for personal use, this means you can't publish the file.
You can recolor mesh files and include the mesh in your download, but give credit and insert the Mesh Read Me file.
