A: The visible spectrum of light goes from the infrared to the ultraviolet. The waves of the infrared are stretched out and move slower than the compressed and faster-moving light on the ultraviolet side. When sunlight (which is slightly yellow) hits our atmosphere, it is scattered by the gases in the air. This compression of the light waves shifts it towards the ultraviolet and gives it the blue color.

When the sun is setting, the light has farther to travel through the atmosphere. The compressed (blue) waves hit the atmosphere and scatter, but the stretched (red) waves continue through. By the time the light reaches your eyes, the sky has filtered the blue part of the spectrum and slowly filters out all of the colors until you’re left with orange, red, and eventually the blackness of night.

This is a really cool optical illusion. This picture only has three colors, and two of them are magenta and orange. The other two colors are actually the same shade of light green. It may be hard to believe, but the blue and green you’re seeing are the same color. The second graphic shows what the picture looks like without the magenta and orange pixels. Maybe it’s just because I’ve seen a lot of optical illusions (because I’m weird like that), but I haven’t seen one in a long time that was as interesting as this. Partly because it’s not black and white, but mostly because it makes most people experience a complete and utter inability to perceive things correctly.

This image only has three colors, and two of them are pink and orange.

This is the exact same image without the pink and orange pixels.
