I was at a pool party this last summer and they served various colored cheese varieties, some blue, some green and red and purple. I was fascinated by this trendy food presentation, and enquired from the hostess where she had acquired them. SHe said her pool company carried them. I stopped in and was astonished by the nifty advertising display with the banner, Cheeses Dyed for your Swims. sorry, I know it is awful!
