How do we see colors? Our eyes are set up so that we have receptors in the back of our eyeballs and some of these receive color signals and some of these receive black and white signals. Now. When at night, I don't know if you've ever noticed this, but at night when you're looking around in a dark area, there's no color. Everything is black and white. But yet, everything has color, but there's not enough light energy there to stimulate the color receptors in our eye. So that when you see things at dark, at dusk, everything seems black and white. If you turn the lights on and you're in a room that's dark, you're going to see black and white first, you turn the lights on, you're going to see bright vivid colors. So our eyes are meant so that we can see in the night with black and white and in the daytime with color. Now, it's good that we have the black and white vision at night because that's actually more sensitive. You can see much more things at night with our black and white vision than you can with color. And another interesting thing, at night if you're looking at stars, if you see a star in the sky, you're best not to look directly at it because if you look directly at it, it's hitting the blind spot in the back of your eye. If you're looking at something in the night sky, look a little bit away from it and just get an angle view at it and you'll see it brighter and you'll see it better.
