Color Perception in the Atmosphere

The video challenges the common belief that the sun is yellow, explaining that sunlight is actually white, composed of all visible spectrum colors. The Earth's atmosphere scatters sunlight, making the sky appear blue and the sun yellow. This scattering is more pronounced during sunrise and sunset, creating vibrant colors. The video also highlights how particles like water vapor enhance these effects.

• It would be yellow

• It would be a transparent window to the stars

• It would be blue

What causes the sky to appear orange and red during sunset?
