why do printers use cyan magenta and yellow instead of rgb
CMYK color model To reproduce color, the CMYK color model codes for absorbing light rather than emitting it (as is assumed by RGB). The 'K' component absorbs all wavelengths and is therefore achromatic. The Cyan, Magenta, and Yellow components are used for color reproduction and they may be viewed as the inverse of RGB. Cyan absorbs Red, Magenta absorbs Green, and Yellow absorbs Blue (-R,-G,-B).[citation needed]
Color in Chinese culture Red, corresponding with fire, symbolizes good fortune and joy. Red is found everywhere during Chinese New Year and other holiday celebrations and family gatherings. A red envelope is a monetary gift which is given in Chinese society during holiday or special occasions. The red color of the packet symbolizes good luck. Red is strictly forbidden at funerals as it is a traditionally symbolic color of happiness;[1] however, as the names of the dead were previously written in red, it may be considered offensive to use red ink for Chinese names in contexts other than official seals.
