Unless I'm missing something with the original post this is very common knowledge.

Don't mind me but this is not quite true.
The "green" (and note that color is just a dye) is ethylene glycol. The pink (again a dye) is propylene glycol. Both are glycol but of different type and the "pink" is less "environmental toxic" than "green". Propylene glycol is compatible with potable water plumbing and food processing chain (even if it is a type of glycol).
