A color space is a way of representing colors and how they
relate to one another. Among the color spaces currently in use,
the RGB and CMYK spaces are encountered very frequently: RGB,
because it is used in color monitors; and CMYK, because it is

different color spaces, and any google search will produce many
results for further study. In the computer industry, RGB has
become the de facto standard for both desktop applications and
web-based systems. RGB is an additive color space - that is, its
three primary colors (red, green, and blue) combine additively
to produce any desired colors. Each of the component colors is
represented by a number from 0 to 255. This representation lends
itself to easy manipulation by computer systems in a hex
notation. It also means that 255 x 255 x 255, or 16,777,216
different colors may be represented in the RGB color space. The
RGB color space may be shown as: This shows that when you have
an RGB value of (255,255,255), y
