I've got a good one, it seems like it should be an easy problem but its not.

A braclet company makes beads by putting them one by one onto a string and then melts the two ends of the string together. The seam is unnoticable to the naked eye and should not be considered in this problem. The company has 5 colors of beads(red,blue,green,white, and black), how many different braclets can they make?
