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. The difficulty is that her webcam adds warmth while the reference photographs she sent were taken under several kinds of indoor lighting. I do not want screen rendering to become the final decision, but I would like the conversation to narrow down sensible shade families before the appointment. I found this online color analysis to organize observations that we can verify later in person. Would matching one simple daylight setup improve the comparison, and is it worth comparing the same image on two devices during the call? The consultation will also cover color history and upkeep. What remote checks have been useful without creating false precision?
