Here's part of the class's palette. This week's homework has us building a simple green mix chart. I botched up a couple of labels across the top but the pure paints are across the top and down the left.
You may notice that there's a split primary palette in here--warm and cool yellows, same for blues. We're using these paints for color matching to the lettuce mix. Sarah says we match to real leaves and not photographs. My grumbling fell on deaf ears. :-)
