Now, this may not be known. But I remember downloading a mod (not sure what one) and it having an object vendor that looked like a green delivery van. In it you could by a cola. I think it was dubbed “blu cola” and when drunk it changed the colour of the player blue.
More info: I think the way to get said cola. you need to buy a amazon-like company box that also allows the user to by a vending machine that sells said “blue cola”.
Would appreciate any info if any.
