Below is a picture of a color wheel. This helps you understand how colors are made.
There are three main colors: yellow, red, and blue. They are called the primary colors. And it is with these three colors that all other colors are created.
When you mix these colors, which you will do in this experiment, you will come up with all the different colors in the world.
What is missing from the color wheel? You notice there is no white and no black because those are neutrals. And actually the color wheel is based on science and how our human eye sees the world. In our eyes there are two separate ways to see light and color and black and white. We have the cones that see color and hence we have the color wheel. And then we have rods which are black and white. When it is daylight all these things mix together in our eyes so we see all sorts of variety. But if you've ever been in a bright room and then you turn the lights switch off and for a second you can't see anything. What's happening is all the color is going out in our eyes and the neutrals (the rods) are starting to show. And then slowly but surely you can see forms in the dark. But in this experiment you will work with the light switch on and you will learn how color plays in our eyes.
