The Color Wheel shows the relationships between the colors. The three primary colors are red, yellow, and blue; they are the only colors that cannot be made by mixing two other colors.
The three secondary colors are green, orange, and violet; they are each a mixture of two primary colors. Their hue is halfway between the two primary colors that were used to mix them.
On the color wheel, the secondary colors are located between the colors they are made from.
The six tertiary colors (red-orange, red-violet, yellow-green, yellow-orange, blue-green and blue-violet) are made by mixing a primary color with an adjacent secondary color. On the color wheel, the tertiary colors are located between the primary and secondary colors they are made from.
Black, white and gray are not true colors (or hues). They are considered to be neutral, achromatic colors.
To integrate this concept into our Many Colored Days unit, we decided to mix two primary colors to create a secondary color!
Using homemade chalk (cornstarch and water), we mixed yellow and blue, and excitedly watched to see the result!
