I'm not sure which charts you are referring to, I know there are a few out there .There is a Genesis paint chart on the forum. look under GHSP recipes then scroll down and look for- check out this link every color u need. Most colors are on there. Also another one is clayalley.com/genchart.htm. I like this one you can make lots of colors using only 5 colors of paint. I don't have the Beyond Basic E book,but in some E books we uses the Genesis red + ultra blue for Crimson. If Lara says use the Genesis red +purple in the Ebook then use the shades she recommends.You just need to play around with your colors and see which one works best for you and the effect you are trying to achieve. Hope this helps.
