Case 17 — Disputed observation: is this dial colour shift real or just lighting?
Suggested protocol. 1) Both dials in one frame. 2) Diffuse daylight, no direct sun, plus a second shot under neutral indoor light. 3) Grey card visible. 4) No filters, no editing. 5) State camera settings if known. If both shots show the same direction of difference, the claim is supported. If the difference flips between lighting conditions, it's most likely lighting.
