So ... where is ... violet?

The secondary colors--Yellow, Cyan (light blue), and Magenta (light purple)--are a combination of two primary colors in equal proportion.

When you mix two primary colors in different proportions, you can generate a continuum from one to the other, a portion of the color wheel. It goes through the secondary color formed by those two primary colors.

We can characterize any color as a combination of four: white (tinting), one of the secondary colors (made up of two primary colors), a primary color (one of those two colors), and black (shading).

Try to match the code with the color's name.
