Blue is my favorite primary color!
I would agree with that. I also like blue. 
The main purpose of RGB is for sensing electronic systems
I don't know what RGB is. Can you tell me more about that?
electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors.
RGB is a "device-dependent" color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual R, G, and B levels vary from manufacturer to manufacturer, or even in the same device over time. Thus an RGB value does not define the same "color" across devices without some
RGB color model
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. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
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. Before the
