This item is a Java simulation that illustrates what happens when the primary additive colors of light (red, green, and blue) are mixed in any combination. It consists of a red, green, and blue circle that can be overlaid and combined by the user in either pairs or all together. It explains why the combination of red, green, and blue produces white light and also demonstrates how the three complementary colors of light (cyan, yellow, and magenta) are produced by mixing the primary colors in pairs. This item is part of a larger collection of materials on optics and microscopy developed by the National High Magnetic Field Laboratory and Florida State University. SEE RELATED MATERIALS on this page for a comprehensive tutorial on the primary colors of light and human color vision.
