Answer for a 6-year-old:
If you add white paint to blue paint, you get a lighter blue. We usually call that light blue or sky blue. The more white you add, the lighter the blue becomes.
How to try it (step by step):
- Put a little blue paint on a plate.
- Add a tiny bit of white paint to the blue.
- Mix them with a stick or brush and look — the blue is now lighter.
- If you add more white, the blue will get even paler.
Five other ways to ask the same question (rephrases):
- What color do you make if you mix white with blue?
- If I put white into blue paint, what new color will I see?
- When white and blue are mixed together, what color appears?
- Mixing white paint into blue paint — what color do we get?
- If you add some white to blue, what will the color become?
