Color Mixtures

Warmup

Activity #1

Experiment With Color Mixing.

In this exercise, you are just going to experience color mixing using the sliders in the applet below.

• Note the three different colors of the circles in this applet by playing with each slider.
• Adjust the sliders to change the level of each of the pigments to experience color mixing.

Activity #2

Investigate Color Mixtures.

A good mixture shows the original colors used and the mixture itself. For example green is a mixture of blue and yellow. In this exercise, you are going to mix colors using the applet below and then create batches of the mixture.

• In the left cylinder, mix 5 ml of blue(click on one time), and 15 ml of yellow(click on three times). You can verify that by clicking on “show amounts?”. This is a single batch of green.

• Answer the question that follow concerning the mixture in the applet above.

Activity #3

Create a Diagram to Represent a Mixture.

In this activity, you are going to create a diagram to represent quantities of each ingredient in a smoothie recipe that calls for 3 cups of milk, 2 frozen bananas and 1 tablespoon of chocolate syrup.

• Create a diagram to represent the quantities of each ingredient in the recipe.

Write 3 different sentences that use a ratio to describe the recipe.

Challenge #1

Using the color mixture above, someone was trying to make the same shade as the original single batch, but started by adding 20 ml of blue and 20 ml of yellow. How can they add more but still create the same shade of green?

Challenge #2

The recipe for Perfect Purple Water says, “Mix 8 ml of blue water with 3 ml of red water.” Jada mixes 24 ml of blue water with 9 ml of red water. Andre mixes 16 ml of blue water with 9 ml of red water.

(1.) Which person will get a color mixture that is the same shade as Perfect Purple Water? Explain your reasoning.

(2.) Find another combination of blue water and red water that will also result in the same shade as Perfect Purple Water. Explain your reasoning.

Challenge #3

Diego makes green paint by mixing 10 tablespoons of yellow paint and 2 tablespoons of blue paint.
