Optics & Eye Health

★Exhibit Content: Three Primary Colors of Light ★Interaction: Electromechanical Interaction ★Operation: Press the start button on the control console, select different lights, observe the color mixing effect, stand in the experience area, and see how the shadows change. ★Exhibit Description: The exhibit features three spotlights in red, green, and blue that project the visitor's silhouette onto the exhibition wall. Visitors can move their bodies or wave their arms in front of the wall, and shadows of different colors appear on the wall. Recommended exhibit for PopsciCat Exhibit Store. ★Scientific Principle: This involves knowledge about the three primary colors (red, green, blue, i.e., RGB) and color mixing. The basic colors that cannot be further decomposed in color are called primary colors. Primary colors can be mixed to create other colors, but other colors cannot be reduced back to the original colors. The three primary colors we usually refer to are red, green, and blue. The three primary colors can be mixed to produce all colors, and when added together, they produce white. Observant visitors may notice that most color displays in our daily lives rely on the three primary colors to achieve color display.
