First, read the English article below.

You already know what to look for in a foundation based on your skin type, and now it’s time to use the knowledge you’ve gained about your undertone to select some possible shade choices. Before heading to the pharmacy or makeup store, consider what foundation bases and shades will look best based on your undertone.  For cool undertones: choose a foundation with a rose, red, or blue base, and consider shades like cocoa, rose, sable, and porcelain. For warm undertones: choose a foundation with a gold or yellow base, and consider shades like caramel, golden, tan, chestnut, and beige. For neutral undertones: consider shades like buff, nude, ivory, or praline. When buying your foundation, look for a store that offers support from beauty experts who can help you choose the right shade and foundation. If that’s not available, look for a shop that has in-store testers so that you can determine the right shade for yourself before you buy. As a last resort, choose a store that has a return policy on cosmetics in case you buy the wrong one. Use the information about the best shades for your undertone and select some foundations to try out. Going by eye, choose a few shades that look closest to your skin tone. Then, test them by dabbing some swatches of foundation on your jawline. The skin at your jawline will be truer to your natural undertone and give you an idea of how the foundation will look against your neck.  If the store doesn’t offer testers, hold the bottles of foundation up to your neck and jawline. Whether you are using testers or just holding bottles up to your skin, find a door or window to see what the foundation shades will look like in natural light. This will also give the foundation some time to dry so that you know what it will look like all the time. The best foundation is the one that disappears into your skin. Foundation isn’t supposed to be seen: it’s supposed to provide an even canvas on which to work. Use the swatches on your jawline to determine which foundation blends in best with your skin....
