Hi, does anyone know how I can alter the color balance / white balance in a photo?

For example, I would like to correct for fluorescent light, tungsten light, and so forth.

Alternatively, I would like a simple way to add R, G, B, C, M, or Y to make adjustments. For example, fluorescent lighting gives a green tint to photos, so I would like to change a photo to add green's complement (magenta) to a photo.

Thanks.

You could try "channel" loads of options:
