  • 1 EA. 8.5 x 11 inch red transparency
  • 1 EA. 8.5 x 11 inch green transparency
  • 1 EA. 8.5 x 11 inch blue transparency
  • 1 EA. 8.5 x 11 inch cyan transparency

  • 1 EA. 8.5 x 11 inch yellow transparency
  • 1 EA. 8.5 x 11 inch transparency containing 6 2.5 inch diameter color wheels

Cut 6 color wheels out of the color wheel transparency. Cut the colored transparencies into small rectangles to demonstrate subtractive color mixing by overlapping cyan/magenta to produce blue, magenta/yellow to produce red, and yellow/cyan to produce green. Demonstrate how overlapping complementary colors of pigment produce black by overlapping cyan/red, magenta/green, and yellow/blue. Demonstrate how cyan, magenta, and yellow absorb a single primary color of light by overlapping the primary subtractive colors and the color wheel: overlapping cyan/color wheel shows how cyan pigment absorbs red light; overlapping magenta/color wheel shows how magenta pigment absorbs green light; overlapping yellow/color wheel shows how yellow pigment absorbs blue light. Use the red, green, and blue films in front of 2 or 3 slide projectors to demonstrate additive color mixing.

4. Item # GASEF 004 Color Wheel Wall Chart Poster

Price: $6.00 ***NEW!!***Consists of 1 EA 18 x 39 inch color glossy wall chart poster.
Order Form for Materials

This large colorful poster will provide a useful reference for classroom discussions of color mixing. The chart provides a side-by side comparison of additive (light) color mixing (on the left-hand side) with subtractive (pigment) color mixing (on the right hand side), so the relationship can be easily seen. The top section of the chart shows the color wheels and primary colors for both additive and subtractive colors. The middle section of the chart demonstrates the science of adding different primary colors of light and pigment, and shows how the color wheel can be used to predict the resultant colors. The bottom section of the chart describes complementary colors of light and pigment, again, in reference to the color wheel.

    • 6 yellow (Y) rectangles: 100% Y, 70% Y, 50% Y, 30% Y, 20% Y, 10% Y
    • 11 black (K) rectangles: 100% K, 90% K, 80% K, 70% K, 60% K, 50% K, 40% K, 30% K, 20% K, 10% K, 5% K

Cut this sheet into 8 horizontal color strips: one each for R, G, B, C, M, Y, and two for black. Overlap and slide the CMYK strips to generate all of the colors that can be generated by a typical color printer. Compare the large range of colors that can be produced using CMY strips to the few colors that can be produced using RYB strips or RGB strips.

Each gradient strip shows a single hue, with different values of saturation. The more colored rectangles have higher saturation than the lighter colored rectangles. Each black gradient strip rectangle has a different value or lightness. The value or lightness of any colored rectangle can be changed by placing it on a black rectangle. So these strips are also useful for discussing the color model of hue, saturation, and lightness.

16. Item # GASEF 016 "Light Matters" poster

Price: $6.00
Order Form for Materials

This unique 17 x 11 inch color poster describes the interaction of light with matter using a picture of the natural phenomenon, a diagram showing the essential physics, and a written description. The poster in divided into three sections. The first section describes the scattering of light by small particles, which is responsible for the color of the sky as well as sunsets. The second section presents examples of the interaction of light with bulk matter, where the light can be reflected, transmitted, or absorbed. Here, the phenomena of specular and diffuse reflection, the dispersion of light by a prism and the formation of a rainbow, and the color of water and leaves are lucidly discussed. The third section describes the emission of light, using a computer monitor and the color of hot objects as examples. The poster includes references for additional information and a section on details and clarifications.
