You may wonder why colors are grouped into different modes. And
no, there’s no racial discrimination involved. For the nature of
design to flow in an organized manner, there are primary colors,
secondary colors, tertiary colors, etc. If you are not familiar
with the family of colors, here is one way of understanding how
they are grouped and how they are used.
The most common color groups are the RGB, HSB (Hue, Saturation
and Brightness), CMYK and CIE L*A*B. Vector and bitmap graphics
are always associated with the RGB and CMYK, so we must
familiarize ourselves with these modes.
CMYK stands for cyan, magenta, yellow and black. The letter K
was taken from the last letter of the color. The first letter
was not used because there are other colors that start with the
letter b. in this way, confusion of the colors will be
eliminated.
CMYK colors are the inks used in the printing process to produce
full-color photographs and designs. In the principle of graphics
design, these colors are called subtractive colors. When you
combine two of any of the first three colors (cyan, magenta and
yellow), it will produce the three primary colors (red, green
and blue), called additive colors. In other words, CMY is the
product of combining RGB and RGB is the product of combining
CMY. When the CMY colors are mixed you will have black. But
there are still other colors produced from CMYK.
Graphics files are best printed in the CMYK mode. CMYK is
referred to as the standard color model, or the four process
color, used in offset printing.
Why do we use CMYK color model? We use this type of mode because
it produces the greatest number of printable colors. But it is
not applicable to all types of printing, particularly when only
a single color is needed and when the spot inks, such as
metallic silver and gold, are used.
All display devices, such as your computer monitor, use the RGB
(red, green, and blue) mode. CMYK is based on printing and ink
absorbing into paper. Before you can have your graphics printed
in CMYK mode, you must first convert the RGB colors into CMYK
colors. This is done through color matching. Color matching is
the process in which colors are used to produce another color
without altering the original color. You can also convert the
colors using the Adobe Photoshop or a desktop printer. In
converting colors during printing you must have different sheets
of film for each color. The sheets must be arranged in the CMYK
format.
