I am preparing a remote consultation for a new hair-color client because the client cannot visit the salon until the day we perform an in-person strand test. I need notes that remain useful when we later compare real swatches. My concern is that her phone camera looks warm while the reference photographs she sent were taken under several kinds of indoor lighting. I would not treat a video frame as a precise color sample, but I would like the conversation to narrow down sensible shade families before the appointment. I am reviewing this online color analysis as a neutral reference for discussing warmth, depth, and contrast. Would matching one simple daylight setup improve the comparison, and is it worth comparing the same image on two devices during the call? I can also ask about previous dyes, fading, and maintenance limits. I would appreciate a cautious checklist from stylists who consult online.
