Question

Suppose that you are a pottery artist and want to create a special color to paint your work of art. Using the primary colors of red, green, and blue (or RGB), combine the three primary colors to create new color schemes for painting your artwork.

1. Describe how you would mix your color mathematically.
2. What subspace would you operate in?
3. List your base vectors and describe them.
4. If you want to vary the intensity of certain colors, how would you do it?
5. What does vector addition do to your color scheme?
6. What does positive scalar multiplication do to your color scheme?
7. Give a vector representation of your favorite color. Explain the steps you undertake to make this color and name it.

Answer 1

The RGB color model is an additive color model^[1] in which red, green and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.

The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography. Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors.
