Unbelieveable

I’m on Jerboa right now but I used Sync before that so once Sync for Lemmy comes out I’m switching back right away

Computer screens emit light, so when your computer shows a green LED next to a red LED, both green and red light wavelengths are sent to your eyes, and your brain interprets this as yellow. This is because your eyes only have red, green, and blue receptors in them, so sending green light mixed with red light is indistinguishable from pure yellow light.

Pigment, instead, works by absorbing light. The trick is that red, yellow, and blue are not the primary colors of light–it’s instead Cyan, Magenta, and Yellow (which look similar to Red, Yellow, and Blue). Yellow pigment absorbs blue light, magenta pigment absorbs green light, and cyan pigment absorbs red light. Therefore, if you mix yellow and cyan pigments together, the resulting mixture absorbs the blue AND red light, so green is the only wavelength left that gets reflected back and picked up by your eyes.

I found a video on it that explained this well with a neat diagram: https://youtu.be/YtH9eXWuf3Y?t=44

My favorite, though, is:

types in password “Password incorrect” goes to reset password “please enter a new password” types in password “your new password cannot be the same”
