2023 Reader Question 117 published on 6 Comments on 2023 Reader Question 117

I feel like with mythical creatures, we’re dealing with so many different eyes that outside of some basics, everybody sees the world a little differently from everyone else. That doesn’t stop David from being mad every time a mammal describes his plumage as “white” though. He SPARKLES, thank you very much.

It’s the last week of December, so it’s your last chance to join the current round PIN CLUB! Join in December and stay on thru February and you’ll get a PHINEAS THE RED pin with an opalescent red mane, and also his best friend RAVI!


Since color cameras are designed to mimic the human eye (they even have some infrared filter to help; it’s a common DIY project to remove the IR filter from a camera to do some IR photography) with red, green, and blue sensors; and screens are designed to fit human vision with red, green, and blue emitters; people who have color perception that extends to the infrared and/or the ultraviolet should find all these things quite frustrating.

It is a source of frustration. Even among people with ‘normal’ vision there’s a diversity of different kinds of ‘red’ cones, such that different people are sensitive to different wavelengths. We all (well, except color-blind folk) see ‘red’ in the spectrum, but we are differently sensitive to different shades.

As a result, about one in twenty or so will insist that computer monitors NEVER get reds right or that reds are never reproduced uniformly across different cameras, monitors, etc.

The same is true of green but to a lesser extent.

Cameras are actually artificially limited to (human) visible range using an internal filter, which can be removed to photograph wavelengths into the IR and UV ranges. You’d still need to figure out how to *display* photographs with a wider range of wavelengths, but our current technology can absolutely both detect and emit wavelengths beyond human visible range :)
