Wow, I am impressed at how utterly the colorist fails–they obviously know nothing about the Four Horsemen. They didn’t even make War be red, which is the one people seem to be able to manage the most.
The horses ought to be (from left to right)
Pestilence / Conquest - white
War - red (he seems to have gotten the pale horse, which most people forget about, so that’s… something?)
Famine - black
and Death on the aforementioned pale (greenish!) horse.
Don’t ask me what color Lio’s horsie ought to be–“brown and magenta” probably suits him fine.
Its hardly rained at all since April this year, the grass is even dying. Very bizarre!
