In the process of creating tools for my team and myself, I started to write down tips related to Art Theory. Now that I have quite a few, I think it is a good idea to share them here. I will try to post one every week here and on my twitter @Lucas_Hug.
Some of those ideas are well known, and other come from personal experiences, in order to improve them, you are welcome to share your opinion.
I would like to thank Kaz adams, Nikita Leshakov, Kary Black and Mynki and Tim Bergholz for their support.
