The last few days I have only spent about an hour a day on these charts, but I plan on making up all my time this weekend.
I finally finished the yellow medium chart tonight and I noticed that there is really hardly any difference between this chart and the yellow lemon chart. Check out the image below for a direct comparison. Because these colors are fairly costly I may remove one from my palette. I just have to figure out which one.

I switched the alizarin crimson and the TOR columns so this is why those columns look different. But, all together these colors are so close that it almost makes no since to have both on my palette.
