I'm excited to take the OCC Watercolor: Intermediate Technicque Class over at OCC. One of the pre-class exercises is to create paint swatches. Here is mine for my KOI Watercolors (sorry that it's side-ways):
Happy that they did this as I didn't think that having a reference sheet would help. But also, the info on the transparancy or opaquesness helped too.
Off to finish more of the pre-class. Looking forward to the rest of class.
