Coordinating a wardrobe while growing out gray hair

[EmmaMype]

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 it help to ask for one daylight photo beside a gray card, 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?
