Color Spaces  Vincent Bockaert,  The Additive RGB Colors  The
cone-shaped cells inside our eyes are sensitive to red, green,
and blue. We perceive all other colors as combinations of these
three colors. Computer monitors emit a mix of red, green, and
blue light to generate various colors. For instance, combining
the red and green "additive primaries" will generate yellow. The
animation below shows that if adjacent red and green lines (or
dots) on a monitor are small enough, their combination will be
perceived as yellow. Combining all additive primaries will
generate white.  The Additive RGB Color Space  The Subtractive
CMYk Colors  A print emits light indirectly by reflecting light
that falls upon it. For instance, a page printed in yellow
absorbs (subtracts) the blue component of white light and
reflects the remaining red and green components thereby creating
a similar effect as a monitor emitting red and green light.
Printers mix Cyan, Magenta, and Yellow ink to create all other
colors. Combining these subt
