I would avoid introducing the second blender node with the pink and blue chips as described in the 2007 article unless you are striving for a darker, tanned texture look.  Of course, you would need to modulate the chip colors to influence the tint.  I like the results but the freckles become rather subtle with the recommended settings from the article.  As you can see, I didn't bother to apply the changes to all the material zones.
