welcome to the addiction! lol
my favorite neutral combo is:
-shroom
-mulch
-embark
i use shroom all over the eye, then mulch in the outer v and crease, and embark as the liner. to give it a little punch to make it darker, you can also use embark in the outer v.
you can substitute mulch for bronze or sable or satin taupe which are dark shimmery browns that are pretty.
i also like paradisco with mulch or bronze. it's a really pretty pinky/coral with gold shadow. it's one of my faves.
don't pay attention to the color swatches on websites where you buy the makeup. lol.
