In each section below, there is a white circle on the left with a smaller, colored circle moving around inside it as well as a fully-colored circle to the right which you will adjust using the two sliders.
The upper slider controls the hue or color and the lower slider controls the saturation or amount of color.
Your goal is to position the sliders so that the color of the circle on the right matches the color left behind in the white space by the spinning circle on the left.
For example, in the first section if you see that the white space around the spinning red circle is turning green when you stare at it, you would adjust the color on the right to the shade of green that you see, as exactly as possible.
