0. The full stack of end-user display down through distribution, editing, and "film" camera applies faithful color management.
1. Every scene contained a hidden color calibration frame that was recorded on-set holding a proper calibration sheet that the end-user's display could apply dynamic color-correction to produce color calibrated to the average lighting conditions that existed on-set.
2. The end-user can choose whether to apply just 0. or also 1.
There is another problem: in filming or editing, by applying color filter "looks" there is currently little in the way of assurances that downstream will faithfully reproduce what was intended. Colorspace profiles were and are a great advance, but they need to be measured, calibrated and validated all the way down so that they're useful.
PS: This article also reminded me of an attack that could reproduce almost an entire image from diffuse reflections of old-style scanned CRTs/TVs, e.g., that ghostly blue glow of TV watching visible from outdoors, but also that imperfect reflections of CRT computer monitors could reveal their contents.
