RGB Lighting

One day, I was bored at my computer and decided to take a closer look at my mouse. This mouse has RGB lighting, meaning it can change between whatever color you could think of. However, the way these colors are produced has an interesting relation to physics. This mouse contains three separate LEDs. One controls the amount of red light produced, one for green, and one for blue, as indicated by the term RGB. Together, if each LED outputs light with a certain brightness, they can form other colors in between the standard red green and blue.

Back to the story, I picked up my mouse which had a yellow color at the time. I decided to shake it around a bit, and noticed that when I did, I could see red and green strips of light. This is explained by a property of light which shows that light of different colors travel at different speeds. For example, red light travels faster than blue light. Knowing how something works is one thing, but seeing firsthand how that effect is achieved is another.
