Clay Color Sphere

Step 1: Color Sphere

The color sphere is a three-dimensional color model. The color sphere represents all of the colors and tones that may be mixed from combinations of red, yellow, blue, white and black.

Step 2: Gather Materials

Red , Yellow , Blue , White and Black Sculpey or another doughy claylike substance.

Clean Surface

Knife

Dry Paper Towel

Damp Paper Towel

Step 3: Roll Out

Roll the colors out into snakes that are approximately the same length and diameter.

Step 4: Divide & Mix

Cut each snake into fifths.
Mix a fifth of yellow with a fifth of red to make orange.
Mix a fifth of red and one of blue make purple.
Mix one fifth of blue and one of yellow make green.
Additionally, mix a fifth of white and one of black to make grey.

Any combination of folding, twisting and rolling will blend the colors together.

Step 5: Greyscale

Cut and mix small chunks of white, grey and black to create a grey scale. Greyscale is the vertical axis of the color sphere. Note the size of the chunks and the length of the scale. The vertical axis represents the diameter of the final product. If the chunks are too large there may not be enough material to complete the project.

Step 6: Equator

The primary colors will be three equidistant points on the equator. The secondary colors are midway between the primary colors. Utilize red, orange, yellow, green, blue and purple to make a hexagon. Mix tertiary colors to fill in the rest of the circle. For a clean product wipe excess clay off fingers when switching between colors.

Step 7: Grey Hues

Work across the circle mixing complimentary colors. As orange and blue are mixed they approach grey. The same is true for any pair of colors directly across from one another in the circle.

Step 8: Value

Place the light half of the greyscale line as the vertical axis and build the light half of the sphere. Mix white with each color to lighten it as it approaches pure white. The center of the light hemisphere is a mixture of white and complementary colors. The exterior of the sphere is colorful the interior is increasingly grey. Once the light hemisphere is created the same technique can be utilized to create the dark side.
