During twilight, when the sun is just below the horizon, sunlight travels through more of Earth’s atmosphere. This makes the sky look pink or orange because blue light gets scattered away, leaving behind warm colors. It's like when you mix red and yellow paint, the result looks pink!
Why It Happens The blue light in sunlight scatters more easily than red or orange light. When the sun is low, it has to travel through more [air](/search?q=air) before reaching your eyes. This makes the blue light scatter away, and the red and orange colors become more visible.
Examples
- A child watching the sunset sees a sky turn from blue to orange.
- During sunrise, the sky looks pink because blue light is scattered away.
- After a long day at the beach, the sky glows with warm orange hues as the sun sets.
