How do I add color to an image?

Carrie was very recently heard to utter:
I was thinking of the paint programs, but as you say it's hard.
Not so much hard to do, you can view up close and put in color by the
pixel, or with the air brush, but hard to do so it looks normal- not
painted. Whatever the image is. Not so hard to look good that way if
it's a cartoon, or shape, logo, or something. But a person, or
scenery- it might even be impossible.

The easiest way to do it for more detailed photographic-type imagery, I
believe, would be to add a second layer in your paint program, set the blend
mode to Color, and paint on that in the colours you want. This would then
recolour the layer below in the colours with which you painted, without
losing the detail.

Hand-tinting is an old artform from the days of B&W photography, it was even
harder then, as there was no digital help available.

Update: I just tried out the instructions I listed in my previous post, and
found that although it is quite difficult, it does work. After a couple of
botched attempts I managed to take a photograph I'd greyscaled and turn it
into something that looked more like a colour photograph than an Andy Warhol
artwork.
