Where to find/How to make tree materials

TLDR; Where can I find free materials to use for trees and/or how can I make them myself.

I’ve been experimenting with Unity’s tree system and I’ve made what looks like a nice tree but the only problem is that I now have no materials with which to give it colour and take it away from the bland, white tree which it currently is. I looked in the Standard Assets, the Asset Store and Online but I could not find any materials to use for my tree (the materials in the standard assets did not work, presumably they were designed for a previous version of unity in which the tree system was different). After my fruitless search, I then decided to try and find out how I could make my own or if that was going to be possible, to no avail. So my question is: Where can I find free materials to use for trees and/or how can I make them myself.

You need to make textures and have knowledge with Phothoshop. This is a little bit harder because is not more game programing but art. There are a lot of tutorials making textures and Materials in the web.(Unity Game Environment Texturing in Photoshop - YouTube)

If you want a free texture source there are some in here:
