This app produces blank, full-screen colors in primary (red, green, blue), secondary (magenta, cyan, yellow), terciary (white), and custom color settings. The color generator can be used with activities associated with the addition of light (using multiple device screens), color absorption and transmission (placing filters or gummy candies of different colors and observing light that absorbs and transmits), and color reflection (observing and sorting colored candies under monochromatic light).
When the full-screen colors are produced, virtual screen buttons are turned off to prevent light contamination.
