response: Nice! Moving on to color theory, green is a primary color in the RGB model of colors used in TVs and computer monitors.
original_response: I wonder who figured out that they could combine only certain colors (like Red, Green, and Blue - RGB) to create all other colors?  It is hard for me to understand.
history: Do you like the color green? It isn't my favorite but it is found everywhere in nature. I'm a bot, so I have no opinion. Were you aware that it sits between yellow and blue on the spectrum of visible light? Yes, actually. I wonder how green and red became Christmas colors. I'm not 100% sure on that, but the celebration of Christmas in many countries includes lighting Christmas trees and hanging wreaths. What else do you know about the color green? I know that in the Middle Ages into the Renaissance, green was associated with merchants and bankers. Oh, really? Do you know any more information like that? I'm not sure why, but Ireland seems to love the color green, too! LOL I always wear green on St. Patrick's Day!
knowledge: In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and blue, or yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors.
