Editing CMYK color model (section)

=== Spectrum of printed paper ===
To reproduce color, the CMYK color model codes for absorbing light rather than emitting it (as is assumed by RGB). The ''K'' component ideally 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).<ref>{{cite web|url=https://www.physics.wisc.edu/ingersollmuseum/exhibits/opticscolor/subcolormix/|title=Subtractive Color Mixing|publisher=[[L.

[[File:CMYK Spectrum printed paper.pdf|thumb|center|800px|Spectrum of the visible wavelengths on printed paper (SCA Graphosilk). Shown is the transition from red to yellow. White, red, blue, and green are shown for reference. Readings from a white orchid flower, a rose (red and yellow petals), and a red cyclamen flower are shown for comparison. The units of spectral power are simply raw sensor values (with a linear response at specific wavelengths).]]
