The answers:
1. Black is a color because it is something you can make using pigments/paint.
Explanation:
Here’s a way to show how black is made: Combine all three primary colors (red yellow and blue) using a liquid paint or you even food coloring. You won’t get a jet black, but the point will be clear. The history of black pigments includes charcoal, iron metals, and other chemicals as the source of black paints.
White cannot be a pigment because it is not a color you can make naturally by mixing the 3 primary colors. Now both theories prove each other wrong so which one do you guys think is right?
