Board Thread:Glitches/Exploits and Reports/@comment-29894870-20161228045558

I've seen a few Youtube videos about making grey wood with two people ( not the hacking way ) and wondered if this was a true glitch or just how to make grey wood? I think if I just had to choose I'd say it's a glitch but when I use rare wood to build, for instance blue wood, I always fill the blueprint with about 60% blue wood and 40% common wood to get a blue wall piece. Is that glitching, or just finding a useful way to make more with your wood? What do you people think, is making grey wood a process to change the wood color or a glitch?
