Most notably Ashe's Volley, Anivia's Flash Frost, and the blue buff rune thingies are all showing up in a green with just a hint of blue. Not sure if this is purely on my end or if its a change they made. Doesn't seem intentional seeing as green doesn't exactly match Ashe and Anivia, and blue buff literally has "blue" in the name XD All other blue colors in the game are showing up fine for me though, just those abilities and the buff so far.

same happened to me.
I had red and blue buff earlier but the blue buff was green.

the oracle elixir eye above my supports head was also a different color, like a transparent glittery color instead of bright pink. glitch? o-o

happened to me, though i will add the the inhibitor crystals on blue team were green, ashe's arrows, nunu's ice ball...

and strangely enough purple teams inhibitor crystals were red. (perhaps a related issue there)

However... should this thread not be in the bug section?
edit: put one up in there, and linked back to this too.
