You can wear pretty much any color on your eyes. It's just a matter of placement. You might want to search for tutorials on placement and blending because I have a hard time believing you can't wear dark brown.
Those are good points. I'll work on placement and blending, @helenabonhamcarter. That dark brown is odd, IIOY...it seems to go on much darker than it looks.
Or perhaps my lighting is bad or I actually do have dark circles...
I have taken to tapping my brush in the powder and then tapping it on a bit of tissue to take off the excess. Then I apply with the lightest touch imaginable, almost to the point that my brush is not touching my skin.
To build upon the placement point, depending upon a thousand variables, you may want to restrict dark shadows to just your crease or outer V. I happen to be one of those who can't do dark all across the mobile part of my lid without it aging me 20 years, so I keep it to the outer part of my eye. I have deep set eyes, so I can safely put a dark color in my crease, but my inner corner needs to light. I cannot use shadow under my eye because, again, it ages me. I stick with light eye liners. I would love to rock a true smoky eye, but it makes me look like an aging rock star.
