In general it's a lot easier to remove artifacts from the color channels than the luminosity channel, without having an obvious detrimental effect on the image.

Do you use Photoshop? If so then try this: Shoot something with a lot of color and luminosity noise (some long exposure at your camera's highest ISO should do the trick). Open it in Photoshop, duplicate the background layer and change blend mode from normal to color. Zoom in on the pixel level and apply gaussian blur to the top layer so the color noise is gone (probably 3-8 pixel blur). This should wipe the color artifacts without hurting the image too badly, but you'll see it leaves luminosity noise. Try to do the same thing with blend mode set to luminosity and you'll see the image degrade much more significantly.
