Is it possible to create a continue spectrum of light between freq1 and freq3 just by adjusting the amplitude of the lightsource ?
A monitor CRT (at least) has for so far I know Red green and blue pixels but no yellow and as we all know by changing the intensity of the pixels one can see all colors.
Mathematical I think it impossible to just by changing amplitude changing the frequency.
...you can recreate the illusion of white...
Mathematical a tried to solve it to create 3 sine waves with 3 frequencies in (audacity sound program) . However when I did a fourier transform in it it gave a continuu spectrum.
If you add 3 sines together and your system is linear, then only 3 sines exist
When an animal sees a computer screen, it doesn’t see the same colours as you do because our monitors only properly work for humans.
When your computer screen is told to produce a certain colour, it chooses the red-green-blue ratio that is the closest in
terms of activated cones to the one the given colour would normally cause.
They still see the same shapes, but the colours may be completely off. I wonder whether scientists who study cognitive abilities of animals by showing them pictures even realize that…
I never considered that animals would see something completely different... based on the resolution of the eyes.. My old cat used to chase the mousepointer...
Call them rugby monitors. If so, then HTML coders and computer programmers will have to put up with a new color coding scheme. Instead of #FFFF00 to get yellow you’ll be writing #000000FF to get yellow. Or write #FFFF00FF to get super yellow! By the way, adding 256 more values for the various shades of yellow on an RGBY monitor means that the monitors will be capable of producing over four billion individual colors.
