Color Wheel Challenge (Adobe Illustrator)

This is mostly for Adobe Illustrator users but it should be interesting to everyone.

illustrator blends for color wheelSomething is wrong with this color wheel. The tertiary colors were created using the Adobe Illustrator blend tool. Fix Illustrator’s calculations. The challenge is to create the perfect color wheel using these 12 slices.

1. Download the original color wheel Adobe Illustrator file.
2. Using the color wheel with 12 pie slices, correct the tertiary colors where needed (the colors between Yellow, Red, Magenta, Blue, Cyan, Green and Yellow).
3. Make note of your corrections by changing the numbers for rgb.
4. Attach your file to with any commentary in the body of the message.


The RGB and CMY spots are pure- you can debate these elements as you wish, but within the program each is maximized while it’s complement is zeroed out. The primary colors are pure and correct. Cyan, Magenta, and Yellow are fixed as the primary colors. Red, Green and Blue are fixed as the secondary colors. This is all dandy until we get to the tertiary colors.

Based on the calculations by illustrator, using the blend tool, the colors just don’t look right.

There’s something about the way Illustrator calculates the colors between Yellow and Green especially that just looks wrong.

The tertiaries, the colors between Red and Magenta and Green and Cyan favor one of the parents. Mostly, Yellow and Green

Find halations of equal balance. Where you see each edge of the tertiary color slice glow with the opposite parent in an equal balance, you have the proper blend.
