i came up with this while tryin to find a good vintagey tutorial that worked well for dark skin, most of the vintage tuts or darkening tuts only work for light skin. this tut works well for both but works more for dark skin.
Also if you find that your final icon is too dark, duplicate the desaturated screen layer and that should lighten it up
