I personally don't wear eyeshadows to work, and just use mascara & liner. But for those of you who want to, here is a quick guide:
1. Browns are your best friend.
All shades of brown and beige look lovely on the eye and are formal enough to wear to office. They suit all eye colors. Maybelline Chai Latte is a good economical option, but the color payoff is just average. I prefer single eyeshadows from both NYX & Jordana.
2. Bored with Brown, look at light grey/khaki yellow as an option.
Light matt grey is another great option for office wear. Or even light khaki yellows (Jordana single eyeshadow in Mimosa). Light shimmery pinks too are good too, but only a few people can carry this color.
3. Steer away from glitter all over the lid.
It will look OOT and tacky in office florecent light
4. Blue & Greens are not an option as eyeshadows
Unless you work for a media office, blues and greens no matter how lightly you apply them, will attract attention in bright white light. Unless that is exactly the reaction you are looking for, Refrain. However you can use blue, green, purple as eyeliners. Make a nice thin liner close to the lashes, that way you have your color too, without going OOT
