Working with color
fdjhgf7643gyfgbdjkhs, 2016-08-12 05:02:25

Is there paint that a person and DVRs / cameras see in different colors?

The other day on the DVR filmed 2 cars after the accident. In the video, one of the cars is red, as far as I and the other person in the car remember, it was yellow.
It is possible that both are confused, but still interested in the question.
Is there paint that people see in one color, but video cameras / DVRs record in another?

In general, sensors see the infrared range better than humans.
Probably seen on the records and the network, sometimes the leaves on the trees look red if the day is sunny and there is no IR filter on the registrar.
It's hard to say exactly what happened in your case.
Try to google the number of the car, maybe you will find a photo of it.

This effect is inherent in all colors in general to varying degrees, due to the peculiarities of human color perception, and the way video sensors work. Video cameras are standardized to match human colors under standard light sources (sunlight, incandescent lamp). Accordingly, with non-standard (with a line spectrum), problems with color reproduction are possible. It also depends a lot on the camera. For example, some do not have an IR filter and have IR illumination.
Total: I have not heard of such colors, under ideal conditions (the spectrum of a completely black body is 5000k, a camera with a spectral sensitivity close to human) conditions, I think this is impossible. The change in colors depends more on the design of the camera and the lighting spectrum. With a customizable lighting spectrum, I think any color can be pulled over a wide range.

This is not only possible, but very common.
The electronic matrix, photographic film and the human eye all have different designs and very different color perception. The whole headache of developers lies precisely in making the matrix see like an eye, although initially it sees in a completely different way :) This succeeds with varying degrees of success.
