Beer that looks like beer

[Whele]

Nothing like a nice frosty pint of beer with a nice satisfying layer of foam on top. Except... with the dynamically colored beverages, this beverage the bartender served you could be any number of non beer liquids! It could even be fertilizer. Gross. To fix this, I think beer served to you in a pint glass should have its own sprite, complete with foam and condensation. I'm aware this is totally at odds with the current liquids functionality, but you really can't beat the aesthetic power and historic social experience of a good looking, frosty pint. 
Also that BBQ sauce chem was added so this would go with it thematically. 
Any coders that could comment on how difficult this would be to implement are invited to do so. I imagine it'd be tough.

I'm fine with some mechanic for foam on top of a pint glass, but definitely not for having that override the current behavior of liquids being different colors in the glass.

Put cyanide in beer, boom you have beer colored poison

I could imagine some sort of special barkeeper equipment that does this; A kind of holo-container that picks a special sprite corresponding to the drink inside (or the drink of which there are the most units). It could give drinks more of their own identity, and wouldn't be super difficult to implement, I reckon. Some other servers have glass sprites change depending on the drink inside, and making this a special container wouldn't interfere with the existing fluid color behavior.

but.. but what if beer foam on a BLUE drink.. i think that would be revolutionary!
(that is to say, beer foams on specific containers but the color inside still stays the mix's)

What if we add a foam option to the dispenser, so any drink poured from it will have a foam top

Would it make sense for everything? Absolutely not, but since when has anything in SS13 made sense? Put foam on tea, lemonade, actual beer, some god awful cocktail born from the deepest reaches of the average tortured mind of a bartender, or a soda. Endless possibilities

Also, the keg auto does this, and it's not available for the shaker cause it wouldn't do anything (maybe with a funny message when you try)
