history: Red is such a pretty color, don't you think? I don't lean one way or the other, I just know that it has a 625 to 740 nanometer dominant wavelength. Oh wow! That's a new one for me! How many different shades are there? I am not sure but red is a primary color on the CMYK and RGB color models. Yep, along with yellow and blue right? I'm not aware of the other colors. The RGB color model is where three lights, blue, green, and red, are mixed together in varying ways to make a wide array of colors. Don't they use that in old projection tvs to produce the screen images? I think so, the main purpose of the RGB color model is for the sensing, representaion and display of images in electronic systems. Cool, cool. So what colors mix with red to make other colors?
knowledge: It was also an important colour in China, where it was used to colour early pottery and later the gates and walls of palaces.
