A pure-white rule passes only when that band is RGB 255, 255, 255; near-white values such as 253 are reported with their exact colour. - **Scene photos:** Room and lifestyle photos have no plain background to measure against, so fill, edges and shadow are marked as not measured rather than guessed. ## Checkers by marketplace.
