This was the RGBYVO geometric and organic shapes. We had to cut and paint 42 different color values on 42 different sized shapes. At that moment I knew what my teacher meant by, "the begining of the class will be clalled Boot Camp" This was not as hard as the gray scale but I did have similar problems with the darker color vaules of blue, red, and purple. I learned that I should use more on my paint brush, watch out for smudges and you only need a little bit of black acrylic paint to make a darker color value.
