If you want to learn more about the MTG color wheel or MTG design in general check out the "Drive to Work" podcast by Mark Rosewater, the lead designer of magic. Dude is wicked smart and very humble.

Drive to Work [1] is a great podcast. Most of it is, of course, about MtG, but there are a lot of episodes about various things like writing, creativity, or communication. Mark Rosewater is the head designer, which means that he is responsible for creating the general structure of a set [2] and not the various stages of fine tuning that happen later on.

So there is a lot of content about designing for humans and little about detailed number-crunching and game balance.

He also explains most terminology and concepts, so a passing familiarity should be more than enough to understand the MtG-related content.

Also, no ads.

Could you or GP recommend a few best of episodes?

Just off the top of my head: Feedback (545, 199), Human Nature (329), Teaching (415), Creativity (77, 551), Complexity (455), Stand-Up Comedy (347, 543), Interviews (335).
