From the thread title, I thought the OP meant the elemental forces that operate in the DC Universe:
The most well known is the Green which govern all plant life and is watched over by the Parliament of Trees. Characters like the Swamp Thing and to a lesser extent, Poison Ivy, have strong connections to the Green.
The Red has domain over all animal life and is led by the Parliament of the Limbs. Animal Man, Vixen and Beast Boy all have connections to the Red.
The Clear or the Blue have dominion over all aquatic life. Not much is known about this but I think they're led by the Parliament of the Waves. Aquaman has a tenuous link to the Clear.
Then we have the Grey, which is connected to all fungal life. No known parliament.
We also have the Rot with its connection to death and decay ... led by the Parliament of Decay.
I got all this from this video : https://www.youtube.com/watch?v=YcIcqfsGP9o
I believe there are other elemental forces not mentioned in the video but I'm too lazy to look them up.
