Painting with CMY Activity Sheet

Overview:

It's your time to order uniforms for the school's football teams. There is one difficulty: the company which you will order from prefers to receive the order in terms of the three primary colors of paints which will be applied to different parts of the uniform. In this activity, you will experiment with the effect of different paint colors on the appearance of the various parts of a football team uniform.

Directions:

Circle the primary paint colors which must be imparted to the following team uniforms in order to create the indicated color appearance:

Team #1: Chicago Titans

 Uniform Part Desired Appearance Required Paint Colors Helmet Blue Cyan     Magneta      Yellow Skin Magenta Cyan     Magneta      Yellow Shirt Yellow Cyan     Magneta      Yellow Pants Blue Cyan     Magneta      Yellow Socks White Cyan     Magneta      Yellow Shoes Black Cyan     Magneta      Yellow

Team #2: Washington Knights

 Uniform Part Desired Appearance Required Paint Colors Helmet Red Cyan     Magneta      Yellow Skin Black Cyan     Magneta      Yellow Shirt Blue Cyan     Magneta      Yellow Pants White Cyan     Magneta      Yellow Socks Red Cyan     Magneta      Yellow Shoes Yellow Cyan     Magneta      Yellow

Team #3: St. Louis Fliers

 Uniform Part Desired Appearance Required Paint Colors Helmet Green Cyan     Magneta      Yellow Skin Yellow Cyan     Magneta      Yellow Shirt Green Cyan     Magneta      Yellow Pants Yellow Cyan     Magneta      Yellow Socks White Cyan     Magneta      Yellow Shoes Black Cyan     Magneta      Yellow

Follow-Up Questions:

1. Indicate the result of mixing the following primary color of paints in equal amounts:

Cyan + Magenta ---->

Cyan + Yellow ---->

Magenta + Yellow ---->

Cyan + Magenta + Yellow ---->

2. What primary paint colors must be imparted to an object to give it the appearance of white?

3. What primary paint colors must be imparted to an object to give it the appearance of black?

4. A primary paint color serves to selectively absorb a specific primary color of light. Whatever light is not absorbed is reflected by that paint. Use your understanding of color addition and subtraction to indicate which primary colors of light are absorbed by each primary paint.

Cyan paint absorbs the primary light color _____.

Magenta paint absorbs the primary light color _____.

Yellow paint absorbs the primary light color _____.

5. Complete the color equations shown below; then indicate what primary paint color(s) are in the object.

1. R + G + B light - ____________ light = R + G light = ___________ appearance; there is ___________ paint in the object.
2. R + G + B light - ____________ light = R light = ___________ appearance; there is ___________ paint in the object.
3. R + G + B light - ____________ light = G + B light = ___________ appearance; there is ___________ paint in the object.
4. R + G + B light - ____________ light = __________ light = Magenta appearance; there is ___________ paint in the object.
5. R + G + B light - ____________ light = __________ light = Black appearance; there is ___________ paint in the object.
6. R + G + B light - ____________ light = G light = ___________ appearance; there is ___________ paint in the object.
