Easy, if you have a high res scanner simply make a color scan of it, then you can blow it up, lighten, darken, etc. just about any aspect of it. If you don't have a scanner take it to a place that scans like any big box office supply and they can do it for you (but don't leave it there! Don't even let it out of your sight and babysit the whole time they have it, some of those min wage employees are morons!). If that all fails you can take a good digital pic and try the same thing, or send the pic to me and I can try to help.
