Determining Your Skin Tone
Before you put on any make-up, look at yourself in a mirror or take a picture, preferably on a white background. You all know what your hair color is, even if you've dyed it, think about your original one. The four skin tones are like the four seasons,
winter, spring, summer, and fall.
Winter: has blue or pink undertones. Your actual skin color could be dark, olive, or extremely pale. You probably have dark hair and dark eyes.
Spring: usually has golden undertones and creamy or peachy skin. Your hair color is either very deep blonde or strawberry blonde. Your eyes are probably blue or green. You probably have naturally rosy cheeks.
Summer: Also can have blue or pink undertones. Your skin tone is probably pale and pink. You also probably have light-color eyes and naturally blonde or brown hair.
Fall: If you have golden undertones and either red or brown hair, you're probably a fall. You also probably have brown or goldish eyes.
Now you know a little bit about the different skin tones. Determining your skin tone is the first step in determining the colors that will look best on you and the ones to avoid. As a reference, I use Beauty and the Bath.com. That site also has a ton of information on hair care, make-up techniques, and a lot of other stuff. Please check it out! I've linked the page for the different skin tones, but from there you can get to the whole website.
Now for example, I am a fall. I have red hair and blue eyes with gold flecks. I should not be wearing pastel colors, especially near my face. They will make me look dull and sickly. However, black can make me look awesome. As a result, I have a few kuro coordinates and no Angelic Pretty prints. Do you know what your color pallet should be now? If the website above didn't help you out, you can google your season and see what comes up. There are tons of helpful sites out there!
