Name the primary colors. why are these colors considered the only “primary colors”?

Red, yellow, blue; these colors are considered the only primary colors because if you combine them together, they make other colors.

Blue, Red, and Yellow are the 3 primary colors. This is due to the fact that, from these 3 colors all other colors can be made from them, but no other color can make the 3 primary colors.
