The problem with adding additional colors lies in limitations in hardware, and limitations in the signal. Adding additional color points beyond this could increase the amount further, but even with an infinite number of "pure" colors arranged radially, you would only get an additional 20% over the hexagonal scheme. Thus, a hexagonal color scheme gives approximately double the amount of color as a traditional triangular scheme. The same could be done for magenta and cyan as well, forming a color hexagon instead of a color triangle.Īrea of a regular triangle: (1/2)(3) R 2 sin(360/3) = (3/2) R 2 (.866) = 1.299 R 2Īrea of a regular hexagon: (1/2)(6) R 2 sin(360/6) = (3) R 2 (.866) = 2.598 R 2 Color spectrum tv#Thus, the RGBY TV has a larger range of colors than the RGB TV, but does not necessarily skew the color spectrum like how altering one of your "pure" colors might. ![]() This allows them to make colors in the yellow spectrum that cannot be reached using RGB. In particular, the quattron TV adds a yellow point that lies radially between red and green, but is pushed as far out as pure red or pure green. The new trend in color is adding additional points to that color "triangle". That manufacturer could then brag about having a deeper array of reds, as they could make colors other TVs could not handle. Back in the days of CRT TVs, some manufacturers used more "extreme" values of red, which skewed their whole color scheme to a more reddish look. That being said, not all makers use the same "pure" colors. Any color on that triangle could be represented. These 3 colors can be thought of as making a triangle between themselves. The reason most monitors and TVs are made with RGB values is the vast majority of spectral colors and several non-spectral colors can be made using these 3 "pure" colors. This is a property that we exploit in computer graphics all the time. Magenta isn't in the spectrum, but neither is brown, maroon, and a whole host of others. They don't exist at any particular wavelength of light, but instead are caused by the overlap of synapses in the occipital lobe of the brain, causing the colors to blend. Magenta is a member of a set of colors we computer scientists call non-spectral colors. ![]()
