Grammar help (correct sentences):
- If you mix blue with green, what colour will you get?
- What colour will the paint be if you mix blue and green?
Note: you wrote "python" — that is a snake or a programming language. I think you meant "paint" or "colour."
Answer: When you mix blue and green you get a blue-green colour. With paint it usually looks like teal or turquoise (like the sea). With light (like on a TV or phone) blue + green makes cyan, a bright blue-green.
Try this: Mix a little blue paint with a little green paint on paper to see the colour yourself!
