I went and talked to a MA at MAC about my wedding makeup (getting married in September) and she suggested doing Brule for the lid color, soft brown in the crease, and Haux in the outer corner. She said it was important to do colors that will bring out your eye color but nothing overpowering or too shimmery.

She also suggested using a blushcreme (I got Brit Wit) instead of a powder blush.

My best suggestion would be to just take your sister into a MAC with you and have a MA work with you on picking out what colors would look good on her. I have the same coloring as your sister (freckles and all) but with blue eyes, so the eye shadow colors will probably be different for her - but hopefully this will give you some ideas!

Mainly I think the idea is to choose neutrals that will bring out her eye color but not over power her.
