COPIC SKETCH MARKER BLUE COLORS

A note on the Copic color system from Too Corporation: 

"The color family is divided into 10 levels of Blending Group (0-9). The first digit in the color number represents the saturation level of each color. More vibrant colors tend to fall in the 0s, 10s or 20s color number. The higher the number the more saturated the colors become and the lower the number, the colors becomes more de-saturated and closer to grey. An increase in the first digit of the color number will show a saturation difference that could create a different outcome."
