For anyone not familiar with the term, organlegging is a word that Larry Niven coined to describe an illegal trade in stolen organs in a science fiction context.

2018-08-05 Rerun commentary: The night time lighting here is pretty good, I think. It's dim and also towards the reddish end of the spectrum, like a lot of low level lighting. We tend to associate dim lighting with a reddish colour, as opposed to bright lighting and more bluish-tinged daylight. Our bodies are even adapted to this difference in lighting colour. Blue light tends to keep us awake, whereas redder light tends to make us sleepy - an effect reported in the scientific literature in 2005.

Nowadays this is fairly common knowledge, and there are many ways to adjust the colour temperature of display screens on your computer, tablet, phone, and TV so that during the day (when you should be awake) it is more blue, while late in the evening it shifts to a more reddish hue, so that it triggers a sleepiness response and you can get a good night's sleep, rather than being awake and tossing and turning trying to fall asleep.

Fortunately for us, the overall hue of a display device doesn't seriously affect our ability to perceive the correct colours of objects being shown on the display, due to the psychophysical effect of colour constancy. This is the ability of humans to perceive the correct colours of objects under different lighting conditions.
