Step 1: Get all your materials ready before starting the WebQuest. You can use paint, colored pencils, or any other materials you're comfortable with.

Step 2: Grab a piece of paper or canvas to work on. Be sure to list all the colors you need to create by mixing. You should label them to keep track of your progress. Remember, you need to create 9 colors by mixing, and you will start with 3 primary colors. In total, you should have 12 colors. 

Step 3: You and your partner will decide how many colors you will create. Make sure both of you agree on who will be doing what. If you're working alone, you will need to mix to get all 9 colors.

Step 4: Begin mixing the primary colors to create the secondary colors. There should be 3 secondary colors.

Step 5: After you’ve created the secondary colors, move on to the next step and mix primary and secondary colors together to create tertiary colors. You should create 6 tertiary colors in total. 

Step 6: Ensure you’ve created all the necessary colors to complete the WebQuest, totaling 12 colors. If you have any questions, ask your teacher or an adult for help.

Step 7: You have the option to share your work in person or online. Once you're finished, turn in your work to the teacher or adult.
