There are also several websites online that will let you "try" them for free. Just google Colorize Old Photos. They aren't terrible; aren't great. Mostly they just put in flesh tones and rely heavily on the color blue. Here's my Auntie Mary, a World War II vet as an example (name of the website used is in the corner). It's an improvement on the black and white, but I really doubt that she was wearing black lipstick. Also one of my mother, which came out better.
