In the previous lesson we learned that the light, which makes its way into our eyes, has been knocked back and forth a lot before we see it.

Q: What is our goal with this lesson?
A: To understand that colour is the sole component in light. we may categorize different characteristics for purposes of communication, but in the end they are one and the same. As well, light is the sole component in something called "the visible spectrum". Surprise, they are all one and the same.

Q: Why is this important to content creators?
A: One of the nastiest things about Colour is that it doesn't behave uniformly. If we are even going to begin to understand why this is so, we will have to take a look at the visible spectrum.
