Show the picker correcting something in the manual

The recording sampled a red brick wall and moved the sliders by three units, which at GIF size is a click that does nothing. The scene now drags the frame cold first and picks a white air conditioner, so the correction is visible and the picker's being absolute - set from the photograph, not from where the sliders were - is what the picture shows. The text says so, and says a blown highlight is refused.
