Swatch the foundation on your chest because usually, it's a closer match to the color of your face.

People with warm undertones look great wearing foundation with orange and gold hues. If you have cool undertones, then your skin has more blue or pink in it. In this case, you'll want to look for a foundation that has more of a bluer-base in shades of red and pink. Neutral undertones have a mix of both.
Blend The Foundation Lighter Than You
When in doubt, always pick a shade that is slightly lighter than your complexion rather than darker. This can prevent your complexion from looking darker than the rest of your body. It is the safest way to go when unsure about two shades that may look too light or too dark.

Consider how sun affects your skin

The right foundation shade should match your skin's undertone. While your skin tone is how light or dark your skin is, the 'undertone' refers to the colours under the surface of your skin and can be warm, cool, or neutral. While your skin tone may change with the seasons, your undertone should remain consistent.
