Let's start by learning about the color wheel. The color wheel is a circular diagram that shows the relationship between different colors. It helps us understand how colors are related and how they can be combined to create new ones.

Primary colors are the main colors that can't be made by mixing other colors. There are three primary colors:

1. red
2. yellow
3. blue

Secondary colors are created when we mix two primary colors together. Let's explore the three secondary colors and how they are made:

1. Green: Mix blue and yellow together.
2. Orange: Mix red and yellow together.
3. Purple: Mix red and blue together.

Tertiary colors are the colors you get when you mix a primary color with a secondary color. The word 'tertiary' means 'third' in order, so these colors come after primary and secondary colors. There are six tertiary colors:

1. red-orange
2. yellow-orange
3. yellow-green
4. blue-green
5. blue-purple
6. red-purple
