Textures from other things?

So, in my new game; Ender’s Journal the game, I wanted to make the blocks the exact textures as the real ones from the original Minecraft game. So, in the first level, I started with oak planks. I pulled up a picture of the real deal, and I tried dozens of times to get the right colors. At this point, it looks like a blob of greenish browns and tans. I need to get the real deal. Any way I could do that on free mode?

Nevermind. L=
