I feel robbed
What blind animals see:
What mastodon users see:
There are two bands of color ranging from Red to Purple. The top one is labeled: “What we see” and the bottom one is labeled “What animals with a larger color range than ours see:”
The joke is that both color bands are the same because the viewer is presumed to be human, and therefore cannot perceive the extra colors.
presumed
There are humans with a fourth color receptor in their eyes who may have a wider color range than your average person.. Women only though, sorry boys.
Took me a moment
Mantis shrimps have the most complex eyes in the animal kingdom and have the most complex front-end for any visual system ever discovered. Compared with the three types of photoreceptor cell that humans possess in their eyes, the eyes of a mantis shrimp have between 12 and 16 types of photoreceptor cells. Furthermore, some of these stomatopods can tune the sensitivity of their long-wavelength colour vision to adapt to their environment. (Wiki)
The wavelength of Magenta doesn’t actually exist. It’s our red and blue photoreceptors activating without the green ones. It blows my mind how many non-existent colors mantis shrimp can see.
