Choosing the right makeup colors...can be so intimidating. I found this video from the Robert Jones Beauty Academy. This is the best visual description I've seen for how to use the color wheel to understand how to make your natural beauty pop. People should see you, not your makeup.
1:31 -- Explains cool and warm colors within the color wheel
2:51 -- Eye shadow techniques based on eye color using the make up color wheel
7:59 -- Robert Jones explains color theory to determine the right color of blush
12:34 -- Lipstick color theory using size of lips and skin tone
Hope this helps make makeup color theory less confusing. What new color are you going to try out?
