Can someone please list these?
Why can't you do this yourself?
You can see it quite well in the episodes.
Blue: environment
yellow: redstone
purple: rule
red: animals
Green: build
Orange: first stick figure
if you mean alan Becker's
Because I can't find enough information myself
With blue I would say alchemy, not environment, because that is far too unspecific.
and Orange, for example, is very good at drawing.
