The first part of Lesson one was to create a color wheel showing full intensity of primary colors (yellow, red and blue) and secondary colors (orange, purple and green). See previous post: Color as Value Lesson One.
The second part of lesson one is to make a value scale overlay that will be used for the color wheel in Lesson One as well as the color wheel you will create for Lesson Two.
Using a compass, draw a circle one inch larger in diameter than the circle you made for your first color chart. My color chart is 7″ in diameter. My value scale overlay is 8″ in diameter. Within that circle, draw another circle the same diameter as your color wheel (7″). Draw an inner circle 1/2″ in diameter. Divide the section between the inner circle and the 7″ circle into eight equal bands of circles. Paint the first band black and leave the outer band white. Paint each of the inner six bands a progression of gray value.
With a protractor, Mark off the circle to form pie shapes alternating 25 degrees and 35 degrees. Using a razor or #1 knife, cut out the 35 degree sections leaving the outermost circle intact. Place the grayscale overlay on top of your color wheel.
Squint at the color wheel with overlay to determine the intrinsic value of each primary and secondary hue. If you have access to a scanner, scan the wheel with overlay (or photograph it) and change the mode to grayscale in your computer.
Compare what you thought the value of the hue is to what the grayscale mode shows as its value.
There is little point to spending so much time making color wheels unless you put them to good use. With your focus on value, not hue, take one or two objects and paint them using only the six pigments, full strength, that you used to paint the color wheel. I have posted a few examples and will add more as time goes by. Feel free to send me your images if you wish them to be considered for posting on the page of examples for Lesson One.
