Ever wondered how to blend two colors perfectly?

Imagine you're mixing paint colors for a painting, wanting to get a shade that's halfway between two other shades.

Think about taking half of one color and adding half of another color. You're creating a new shade that smoothly transitions between the two original shades.

Example

If you have red (255,0,0) and blue (0,0,255), mixing them equally gives you purple (127,0,127).

Remember this

This is the concept of a convex combination, blending colors smoothly.
