2. The RGB Model

Around the mid-1800s, photographers began to experiment with different color filters for colored photographs. In the 20th century, the model was complete, and the RGB color model became commonplace. Its name comes from its three primary colors: red, green, and blue. The RGB model uses different combinations of these three primary colors to create various other colors. Under the RGB model, the light of two complementary colors at full intensity will create white light. The complementary color pairs for this model are green-magenta, red-cyan, and blue-yellow.
