1. Radial designs have visual movement or energy towards a center point. Color wheels demonstrate how hues are interconnected in a radial pattern.

2.  Radial designs are common in nature.  The snail shell is an example of a radial design. The pattern “radiates” out from a center point.  Our eyes follow the rhythms/movement of the pattern.

3.  Spider webs are an example of CENTRIFUGAL radial design. Directional lines extend from the common center.  A sliced orange is an example of centrifugal design.

4.  Starfish are great examples of radial design because they can be cut into a “pie”. Another prime example of centrifugal design.

5.  Petals that radiate out from a common center also demonstrate centrifugal motion.

6.  Occurs when further rotational movement is detected. The inside of this sunflower demonstrates centripetal motion.

7.  Concentric designs occur when one shape repeats itself inside of itself. A pebble dropped in water creates concentric circles.  Tree trunk rings demonstrate concentric radial pattern.  Sliced onions also show concentric pattern.

8.  Color wheels demonstrate radial pattern because the colors will build off each other and relate to each other.

9.  Rose windows in Medieval Gothic cathedrals were a sophisticated attempt by man to demonstrate the fantastical properties of radial design. Often at the front of churchs, they were difficult to construct and very expensive.

10.  Inside the complicated tracery pieces of colored glass were inserted to reflect brilliant sunlight into the cathedral in a colorful radial pattern.

11.  Create a color wheel using only primary colors and white and black tempera paint.  Use the primary colors to create secondary colors.  Use the white and black to create tints and shades.  Arrange the tints and shades around the center stripe to create a value scale of light to dark.

12.  Create secondary colors by mixing two primaries (1+1=2)

13.  When you add a color to white, you create a tint.  When you add black to a color, you create a shade.  Always add the darker paint color to the lighter one (ie, add the color to white, or black to the color, otherwise it will use too much paint to achieve the end result).

14.  You will then cut up your color wheel placards and glue onto paper to create a unique radial design inspired by Rose Window patterns.

15.  Demonstrate value gradation within individual hues.  Practice good craftsmanship and paint neatly- don’t leave unpainted spots, paint with clean lines.  Cut neatly and glue neatly and evenly.

16.  In your sketchbook, create a unique optical illusion radial design. Use black and white for high contrast or use color for fun!  Address the whole page.  Use any type of radial pattern you choose.  Use markers, colored pencils, be bold!  Abstract/non-objective subject, here!
