When is it appropriate to perform a test color swatch on the client?

• A. After the procedure
• B. During the procedure
• C. At the end of the session
• D. Before the procedure to preview color on skin, behind the ear or inner forearm, with a patch test

Answer: (D)

Previewing pigment color with a patch test before starting helps you see exactly how the chosen shade will look on the client’s skin and under typical lighting. This step lets you account for undertones, skin tone, and how the color will heal, so you can select the most flattering shade or adjust it if needed. It also serves as a safety check for sensitivities or allergies to pigments or additives before any procedure begins, reducing the risk of an adverse reaction during or after treatment. Doing this test before the procedure gives you the chance to confirm approval and set expectations with the client. If you tested during or after the procedure, you wouldn’t have a reliable preview to guide color choice or catch a potential reaction early, which could compromise results and safety. Common patch test sites, like behind the ear or on the inner forearm, are used because they’re representative, easy to monitor, and convenient for reviewing the reaction and appearance.
