Final answer:
A foundation that is too light will make the skin appear brighter and can result in an ashy or washed-out look. It's crucial to match foundation to one's skin tone for a natural appearance.
Step-by-step explanation:
If the foundation color chosen is too light for a person's skin tone, it will appear brighter than the natural complexion. When selecting makeup, it's important to match the foundation closely to your skin color to achieve a natural look. A foundation that is too light can make the skin appear ashy or washed out, and does not blend seamlessly with the skin.
