QOL: change Vending Machine/Critter chat message colours

[YoukCat]

Have it start out as normal black text, but every time you hear a vending machine it becomes more and more gray until it's in your "subconscious". Then put some subliminal messages in the style of They Live you can only hear at max subconscious.

and then the next thing you know you're part of a Vending Machine cult, constantly forcing others to eat Discount Danns at great, cheap prices.
