Red Buff Area not red enough
I've been checking out all the pictures and videos of the SRU and read about the ideas of readability and cohesion and how both have influenced the update.
Let me start by saying that the blue buff area looks fantastic and in terms of readability, summoners will definitely know where they are on the rift. Looks fantastic.
Red buff area doesn't have that, though. It doesn't need to parallel the intensity of the blue area's coloration, but maybe even adding some small, red, glowing runes behind the monsters and making the vegetation along the jungle lanes more red/adding more for better readability.
All in all, the update looks great. Keep up the great work, Riot.
