after heating, it's precipitate turns from flesh to red.
Millon's test is given by any compound containing a phenolic hydroxy group. Consequently, any protein containing tyrosine will give a positive test of a pink to dark-red color. The Million reagent is a solution of mercuric and mercurous ions in nitric and nitrous acids (CAUTION: MILLON'S REAGENT IS HIGHLY TOXIC AND HIGHLY CORROSIVE). The red color is probably due to a mercury salt of nitrated tyrosine.
Millons reagent is not a compound but a mixture. It is made by dissolving mercury in nitric acid. There is a variant which Millons, Coles reagent which is a LITTLE safer as it uses sodium nitrite and sulfuric acid with mercury. The chemistry is a bit obscure- some say that it involves mercurous ions and nitrous acid. The end result is a nice red color.

You probably mean Millon's reagent. Millon's reagent is a solution of mercury in nitric acid which is used as a test for the amino acid tyrosine. Since proteins contain tyrosine, it is also used as a test for protein. When the test solution is boiled with Millon's reagent a white precipitate (solid) is produced which coagulates and turns red.
