Comment | @Ruth: You are mixing two colour systems, since Blue, Red, Yellow is neither CMY nor RGB. CMY is cyan, magenta, yellow and RGB is red, green, blue. The end result is the same, the colours are mixed to produce all the colours we see in a picture, but they are either mixed from the first three or the second three, never from both. To explain the difference, here a quote from the Adobe homepage: "The secondary colors of RGB, cyan, magenta, and yellow, are formed by the mixture of two of the primaries and the exclusion of the third. Red and green combine to make yellow, green and blue make cyan, blue and red make magenta.
The combination of red, green, and blue in full intensity makes white. White light is created when all colors of the EM spectrum converge in full intensity.
The importance of RGB as a color model is that it relates very closely to the way we perceive color with the r g b receptors in our retinas. RGB is the basic color model used in television or any other medium that projects the color. It is the basic color model on computers and is used for Web graphics, but it cannot be used for print production.
CMY(K) Cyan, magenta, and yellow correspond roughly to the primary colors in art production: red, blue, and yellow.....Just as the primary colors of CMY are the secondary colors of RGB, the primary colors of RGB are the secondary colors of CMY." |
