The primary colors are the first colors, the most basic colors that cannot be made by mixing any other colors together. Those colors are red, yellow, and blue. Yellow is a primary color. Blue is a primary color. Repeat until firm.
Demonstration Take the glass container filled with water.
Using the eyedropper, put in a few drops of blue and have students take a good look at the color. Slowly add a few drop of yellow, and have them watch to see the color green result. Do the same to produce purple, and finally produce brown. Discuss the various colors and suggest that the children might want to do this at home with their families in the kitchen, and they can experiment to see how the shade of green would vary, for example, with the amount of yellow they add to the blue. Orange is a secondary color.
