What cosmetics are most important and what colors?

My small company is wanting to expand and would like to know what cosmetics are most important to people ( i.e. lipstick, lipgloss, blush, powder, foundation, eyeshadow, liner) what colors would you like to see? We currently do not offer foundation because most people are pretty set in their ways in terms of foundation do you think we should start making foundation? What color eyeshadows would you like best?What cosmetics are most important and what colors?
I think you should start making foundation. It just perfects the look and makes it look finished and polished. I ind that eye shadows are very important. The eyes in my opinion can make or break the look of the person. For me I like the blues and purples for the eye shadows. Also bronze and golds. But pink is a must have, because it's a generic colour that most love. Good luck with this! :DWhat cosmetics are most important and what colors?
All of it is very important, but I think you should offer eyeshadow pallets, like the 120 pro pallet from beauties-factories.com
