These were done by 7th and 8th grade everyday students. They worked very hard on them for several weeks. They are quite large. The guitars are life size and the color wheels are 14" diameter. I saw the color wheel guitar idea here at the dieviantArt and tweaked it for our assignment needs.
Students had to either design a color wheel wedge slice with four sections and then trace twelve times or they had to draw their guitar body neck and head and divided into twelve sections then divided into four sections.
In each section students had to mix the parent color, a tint, a shade and show the complementary color of the parent color.
I allowed the kids to use: Red, Yellow, Blue, White, Black and Magenta tempera paint.
To top it off each student had to paint a gray scale for either the neck of the guitar or that corresponded with the content of their color wheel design.
more to come in the next few days
