All eyeshadows have warm undertones and 85% of women need a warm undertone. You cannot shape the eye with a color (example: blue) you must neutralize it first with a warm color. Eye makeup does NOT need to match your clothing anymore. Also, don’t wear blue eyeshadow because you have blue eyes. You CAN, but, it won’t intensify the blue. Most people think it will make them stand out more. It won’t make the color stronger.
