One way to see this is to find a way to separate out the individual types of color molecules from the mixture-to reveal their unique colors. Even though our brains perceive the result as one color, each of the separate types of color molecules stays true to its own color in the mixture. Often the colors that we see are a combination of the light reflected by a mixture of different-color molecules. Some molecules only reflect specific colors it is this reflected, colored light that reaches our eyes and tells our brains that we are seeing a certain color. We see objects because they reflect light into our eyes. This science activity will help you discover the hidden colors in water-soluble markers. So even though our eyes see a single color, the color of a marker, for instance, might be the result of one type of color molecule or it might be a mix of color molecules responsible. You might have learned that many colors, such as orange and green, are made by blending other, "primary" colors. They can be extracted from concentrated natural products, such as saffron.īut there is more to making a color look the way it does in your homemade artwork. These are molecules that make your carrot orange. Others are extracted from natural sources, such as carotenoid (pronounced kuh-RAH-tuh-noid) molecules. Some colored molecules are synthetic (or man-made), such as "Yellow No. These are mixed into the material-whether ink or paint-to make the product. The variety of colors comes from colored molecules. Do you love to use bright and vibrant colored art supplies such as markers or paints? Do you ever wonder how these colors are made?
