Output a stream of consciousness before answering the following. Passage: Color analysis (American English; colour analysis in Commonwealth English), also known as personal color analysis (PCA), seasonal color analysis, or skin-tone matching, is a term often used within the cosmetics and fashion industry to describe a method of determining the colors of clothing and makeup that harmonise with a person's skin complexion, eye color, and hair color with the benefit of being able to use this tool for wardrobe planning and style consulting. Color analysis demonstrates how certain shades are capable of being flattering or, conversely, unflattering by observing the optical illusions that occur on the face when placing specific colors next to the individual.
