1️⃣ The Sun is actually white

• The Sun makes all colors of light.
• When all colors mix together, they look white.
• In space, astronauts see the Sun as white, not yellow.

---

2️⃣ Earth has air around it

• Earth is wrapped in a blanket of air called the atmosphere.
• Sunlight must pass through this air before reaching our eyes.

---

3️⃣ Blue light gets scattered

• Sunlight has many colors: red, orange, yellow, green, blue.
• The air scatters blue light in all directions.
• That scattered blue light makes the sky look blue.

---

4️⃣ The remaining light looks yellow

• After blue light is scattered away,
• The light coming straight from the Sun has more yellow and red colors.
• That’s why the Sun looks yellow to us.

---

5️⃣ Why Sun looks red in the evening?

• In the morning and evening, sunlight travels through more air.
• Even more blue light is scattered.
• Mostly red light reaches us → red or orange Sun 🌅
