I think so, the main purpose of the RGB color model is for the sensing, representaion and display of images in electronic systems.
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?
The main purpose of the RGB color model is for the sensing, representation and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography.
