You have probably seen these color wheels in the store. I pull mine out occasionally when designing a project but when I'm out and about painting I need a tool specific to me. One using colors of my palette and on the paper I am using. Now at home I have a binder filled with test sheets for reference and you can put in a little test swatch right on one of your sketchbook pages but why not take it a step further. Trace and cut out a circle that will fit onto your sketchbook page. Make it out of the same type of paper or as close as you can get. If you have a coil binding you can just rip out a blank page to use. Trace on a smaller circle so you have an outer rim where the colors will go. Using the your palette, here I'm using my field kit, make a color wheel. I like 12 sections: - 3 primary (Red, Yellow, Blue) - 3 secondary (Orange, Green, Purple) - and 6 tertiary ( primary and secondary mixed together, i.e. greenish yellow) On a page of your book draw a window that will show 4 analogous colors at once. Analogous colors are colors that sit side by side on the wheel. Also make a little window that will only show one color directly opposite the middle of that other window. I used the same circular objects I used to trace out the wheel. You want your windows to be a bit smaller width wise that the actual color segments. Using scissors or a paper cutter cut out your windows. Poke a hole thru the center of your wheel, put it in place on top of your window page and mark the center thru that hole. Poke a hole thru that page, insert paper fastener, put color wheel on at the back of that page. Now you have a very useful tool. It shows a 4 color analogous scheme as well as a contrast or complimentary color that goes with them and it's right in your sketchbook at your fingertips. Turn the wheel and you get another color scheme. Applications: - have your students construct this color wheel tool and then picking a color scheme paint a composition limited to these colors. - paint side by side color sketches, one with only analogous colors and one adding in that complementary color. - use the complimentary color for the focal point - use this tool to analyze how other artists utilize these color schemes.
