Wednesday

Today we're going to learn a new way to code for color. In our previous class, we used plain English names for colors. And, in general, you are welcome to continue using them. You can find a reasonably complete list of those color names by searching this collection of charts. It gets a little tedious, though, and I think you're much better off learning the HSLa color wheel, since it is quickly adjustable on 4 different axes and all you need to remember are the number of degrees in a circle (360) and the prismatic sequence of colors from red to purple.
