Basic Color Principles
Color is a very important part in making graphic design
choices, therefore it is important to be aware
of how colors mix with one another to produce other colors. All colors
are made up of three components: Red, Yellow, and Blue, they are known
as "primary Colors"
.
By mixing pairs of primary colors you can produce another kind
of basic colors, known as "Secondary Colors",
like orange, green, and violet. Yellow and red make orange. Red and blue
make purple and blue and yellow make green. By further mixing of the two
secondary colors you can produce "Intermediate
Colors".

The image shows a color wheel with twelve segments displaying the primaries,
secondaries and intermediates.
Complementary Colors
Refers to colors that are 176 degree opposite from
each other on the color wheel. These colors are
in extreme contrast to each other. Red and green, or purple and yellow
are complementary colors.
Other color Properties
1. By adding white you can lighten
your result which is known as "Tint".
2. By adding black you can darken the result creating what is called "Shades".
3. "Hue"
distinguishes one color from another color.
4. "Value"
identify the amount of light or dark within a color.
5. "Intensity" refers
to saturation or chroma, also known as brightness.
CMYK Color
The CMYK color is what we use when printing in full
color, an it stands for: Cyan, Magenta, Yellow, and black. CMYK colors
are also known as subtractive color meaning cyan, magenta and yellow are
mixed in equal intensity and make black.
RGB Color
RGB stands for Red, Green, and Blue and these colors
are also known as monitor colors. RGB colors are also known as additive
color because when red, green, and blue are mixed together in equal intensity
make white. RGB color comes directly through the monitor, straight into
your eyes. Web pages are always displayed on a monitor, as a result every
image you create for a web page should be saved in the RGB mode.
Browser-Safe Color
Also, known as web-safe color are only 216 colors that
are common to the browsers and operating
systems of different computers. If you use any other color outside the
common 216-color palette,
the browser will convert the odd color to the closest color it can find
in the system palette, or it
will mix several colors an in that way to match the
odd ones as closely as possible.
