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.
