Color charts are often used as a means to an end. A way to get to know paints & how they mix with one another. A way to develop a color vocabulary or a palette for a painting. But they are gorgeous in their own right.
There was a time when I made impulsive purchases, not knowing that it was the color that I needed rather than the objects. When I realized that, & when acquiring things was no longer a part of my lifestyle, playing with color
became the way to satisfy my craving.
One of the first published artist's sketchbooks I ever saw was that of Sara Midda.
How imaginatively & sweetly she plays with color, as well as creating a beautiful diary.
Midda's color charts.
What got me thinking about all this color was the Quiller Color Wheel that was introduced in my art group. It can be used in a very technical way. I was never big on science, but for my 7th grade science project I made a huge oil on canvas color wheel. So now (a "few" years later) my challenge is to integrate some "scientific" & organized experimentation with my more spontaneous approach. Hmm...
