response: 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.
original_response: Yes, the RGB color model is an additive color model.
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?
knowledge: The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors.
