most photolab uses the tranditional chemical process even for digital prints, it also go thur the filteration just as film neg. does. there's two way to avoid the problem u got, 1st way is simply look at the prints u got and spot wutever colour problem u got and tell them the problem and have them to reprint it (most big lab would do it for free). the 2nd way is except for pro level labs like london drugs, most big labs like costco nvr change their filter setting, they had a standard filter which would suit most cases. for example, the costco lab nearest me's print r always too blue, so u can print a sample print from them and try to match your monitor's colour w/ their meachine. just like u match ur monitor w/ your own printer.
