if there was going to be any color at all, then I think the brewery info on the sides could be a very dark blue/purple. that might look nice. But I think the main part of it should stay black and white
If I were going to do some color, I could do something like the color changing depending on the style of beer. Gold for a wheat, red for a red ale, and so on.
So, color depending on style, or stick with the B&W?
