Likewise. I haven't seen a color-wheel based magic system yet that models the card game well. I think WotC's decision to effectively ignore the color wheel in their D&D/Magic crossovers is the best choice yet. It's been a while since I've read any Magic lore (novels, webstories), but I'm pretty sure the idea of a "blue mage" isn't really supported in the fiction either. Which mana colors each Planeswalker or magic-user has affinity towards seems to be behind-the-scenes type of stuff rather than explicitly the way characters see magic in-universe.
