About color management
Because the RGB and CMYK color models use different methods to display col-
ors, each reproduces a different
gamut
, or range, of colors. For example, RGB uses
light to produce color, so its gamut includes neon colors, such as those you'd see
in a neon sign. In contrast, printing inks excel at reproducing certain colors that
can lie outside the RGB gamut, such as some pastels and pure black.
