The McKee and Brothers Co began in 1853 in Pittsburgh, PA.  In 1888 the company moved to a town that was ultimately named Jeannette (PA) for the wife of McKee's founder.  In 1903 the company was renamed McKee Glass Co. and that stayed until 1951 when they became a division of the Thatcher Glass Co.  McKee introduced color to its lines in the early 20's.  Their colors were yellow, blue, custard, amethyst, black, white, amber, canary, green, pink, ruby, orchid, jadite and various shades of each.  A number of their white pieces were decorated; and such decoration included "dots" and "ships".  In the photo below the measuring pitcher is Seville Yellow but the shaker is custard.   The pepper shaker is actually more caramel than custard.
