< is pondering whether a computer monitor would work on animals other than humans, and what it would look like to them.
< knows that human eyes can only detect red, green and blue light and that we can see other colours by detecting the levels of RGB light given off by colourful objects. That's why monitors can trick us into thinking we're seeing other colours such as yellow by only using red, green and blue pixels, as they stimulate our cones in the same way a yellow object would. However, what about animals with eyes that detect other colours, like a dog? If the cones in their eyes do not detect either red, green or blue light, then would the mechanism of an RGB monitor still work or would you need differently coloured sub-pixels?
< is reminded of <'s grandma's cat which gets excited whenever there's a nature program on TV, so maybe there's more to it than < thinks.
