Question

Why?

Answer 1

You have a sensor for red light that when stimulated reads that stimulation as red color which it then displays,

However a sensor without filtering for infrared light may be stimulated by the remote and then making it think it needs to display red.

If you and a colorblind friend are working on a painting and you see something red, if you tell that friend to add it to his painting he might use green which most red things have, however if he looked at the object himself he couldn’t see anything. If he then shows it to someone else who is color blind they may notice this green blob where nothing is normally. The full vision friend who’s seeing red caused the confusion because he couldn’t differentiate what colorblind people (us in terms of infra-red vision) see
