I need to gather useful color information during a remote consultation 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 am avoiding firm conclusions from compressed video, 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? I will separately record prior treatments and maintenance preferences. How would you keep this efficient while leaving the final choice for the salon?
