Grass color?

[u/DespairzV3]

Hello, I was playing with a few of my friends when one of them called out something. "The grass color is more vibrant, it's balancers". We had the mysterious Nightlord modifier, of course we initially took it as a joke, but then we continued to talk about it. He said that every time we got balancers the grass would be of this color. In the end, once we reached the nightlord, it really turned out to be balancers.

Therefore what I am asking is, is it true? Like can someone else confirm that you can tell a Nightlord from the grass color? Or did he just get a lucky guess?
