What color is commonly used to match all skin tones?

The color that is commonly used to match all skin tones is peach. Peach is versatile and has a warm undertone that complements a wide range of skin tones. This makes it a popular choice in cosmetics, especially for products like foundation or blush, as it flatters both lighter and darker complexions without clashing.

Red, yellow, and brown, while they can be used in various cosmetic applications, do not provide the same level of universal adaptability to match skin tones. Red can often appear too vibrant or stark against certain skin tones, while yellow might not harmonize as well, especially for those with cooler undertones. Brown can vary significantly in shade and may not suit everyone, especially those with lighter skin tones. Therefore, peach is favored as it tends to blend well with the natural hues found in various skin types, offering a more natural and flattering enhancement.
