Did you know that in light, the primary colors are red, green, and blue? It doesn’t work the same way as paint colors do. When you mix yellow and blue light, the result is white; when you mix red and green, it makes white; and when you mix blue and red, it makes white.
Color television and computer monitors use the three primary colors of light to display millions of different colors. If you take a magnifying glass to your computer monitor or television, you will see a regular pattern of red, green, and blue lines or dots. Each of these glows at varying intensities, and what you are perceiving is the mixing of the primary colors and up to 16.8 million different colors on the screen.
