Fine for me (red/green deficient).

Just don't put masses of white between them and it's less of a problem; if we can see the dividing line between the colors (and if colored it's dark red or black or something in that region), we can usually at least tell they're meant to be differentiated, even in the event that the colors look identical to us, but  if there's whitespace in-between, all bets are off.

PS: Wait, 3 shades of green? I see two greens and 3 blues…
