I think the yellow looks quite different.
However, people with most sorts of color-weakness or color-blindness will disagree.
agreed, the yellow looks fine to me, but many people have problems distinguishing green from yellow at a glance, especially when both are at low saturation, like in this ui. and blue is probably a bad idea because much of the ui / background itself is a light blue.
what about a pink-ish purple? it might not be the most intuitive color for "ally", but i think neither is yellow. and it should provide good contrast to both the player's green and the hostile's rusty orange.
although ultimately all three parties can still be distinguished solely on the square, rhombus and circle shapes, even for people who wouldn't be able to see colors at all.
