THE KARDASHIANS Threatened With Lawsuit Over Cheap Trick

The Kardashians have been accused of a cheap cover-up, stealing the name of a high-end make-up line and slapping it on their own drugstore brand ... so claims the dude who sells the fancy products.

Kim, Khloe and Kourtney are launching Khroma Beauty ... a cosmetics line you can get next month at not-so-fancy places like CVS, Sears, and Ulta.

Michael Rey, the co-owner of Chroma Makeup in Bev Hills tells TMZ ... his brand took 12 years of blood, sweat and tears to build and now boasts an A-List clientele -- but he grouses the Kardashians line cheapens his products and creates confusion in the marketplace.

Michael has drafted a letter to his customers making it as clear as concealer -- Chroma in NO WAY is associated with the "low-budget cosmetic products" the Kardashians are hocking.

We reached out to the Kardashians. So far, no word back.
