I use PS for vectoring, so I just use adjustment layers to get the pic into shape (brighness/contrast, hue/sat, color balance) if I'm going to sample colours directly from the source.

But with really low-res images of really small image size that were recorded presumable from a 1970's videotape the sources really lack all the aspects you need for vectoring (colours, image definition etc) so a lot of the time it's all guesswork.
I'm always surprised when I grab a colour from an image with the eyedropper and it always comes out grey.
