colors in relation to one another. A color circle, based on
red, yellow and blue is traditional in the field of art. Sir
Isaac Newton developed the first circular diagram of

studied and designed numerous variations of this
concept. There are various classifications such as

which is concerned
with painting
Primary colors
comprising of light
which is more concerned
with computers

13. The PRIMARY COLORS:
• All colors are obtained by mixing primary
colors
• Red, Green and Blue are the primary colors.
• They are also called basic colors because
all other colors are obtained by mixing these
elementary colors.

14. • However, these are the primary colors
of pigment, or paint and crayon. The
primary colors of light are red, green
(not yellow) and blue, commonly
referred to as RGB.
• The pigment color system does not
apply to computer monitors because
colors are created on monitors by
adding light.

15. Secondary Colors

primary colors is termed as secondary color.
• Yellow + red = orange,
• Blue + yellow = green,

system for creating a
whole range of colors
from a small set of
primary colors.

20. CMYK model
• CMYK is the color model associated with
color printing and therefore, is has no
relevance where web graphics are concerned.
• Note that only cyan, magenta and yellow are
used below. Black, the fourth process ink is
used to darken the colors created by the other
three process colors.

22. RGB Model
• The RGB model forms its gamut from the
primary additive colors of red, green and blue.

forms white. Computers generally display
RGB using 24-bit color. 16,777,216 possible
colors

blue components is represented on a scale
from 0 to 255 with 0 being of least intensity
(no light emitted) to 255 (maximum intensity).

24. Indexed Color
• Because the palette is limited to a
maximum of 256 colors, it is not possible
for an image to look as realistic as it can
use RGB or CMYK. Hence, they are not
true colors. This type of color is known as
"Indexed Color" because colors in the
palette are referenced by index numbers,
which are used by the computer to identify
each color.

25. Color
Separation
• Color separation
refers to the act
of decomposing
a color graphic or
photo into
