Every time I see a product that introduces using the colours of magic for spells, they always seem to ignore the various effects assigned to the colours. The Tap Untap Burn supplement for instance assigns cure wounds to green when it should really be white (or perhaps white and green, both have healing effects) and they have moved earth type spells which should be red over to green as well. I'm sure they did it to spread spells out over the colours a bit more but it just seems to me that they've missed the point of the established colour system and what each colour represents.
