This presentation looks at basic colour theory and the critical difference between additive and subtractive colour.

3. An Overview of Colour Systems
Subtractive colour model explains the mixing of
paints, dyes, inks, and natural colorants to create a
full range of colours, each caused by subtracting
(that is, absorbing) some wavelengths of light and
reflecting the others.
Additive colour describes the situation where
colour is created by mixing the visible light emitted
from differently coloured light sources

4. Subtractive Colour
When we mix colors
using paint, or through
the printing process, we
are using the
subtractive color
method.
Subtractive color mixing
means that one begins
with white and ends
with black; as one adds
color, the result gets
darker and tends to
black.
The CMYK colour system is the
colour system used for printing.http://en.wikipedia.org/wiki/Subtractive_color

5. Additive Colour
Additive colour
describes the situation
where colour is created by
mixing the visible light
emitted from differently
coloured light sources
If we are working on a
computer, the colours we
see on the screen are
created with light using
the additive colour
method.
Additive colour mixing
begins with black and
ends with white; as more
colour is added, the result
is lighter and tends to
white.
The RGB colors are light primaries
and colors are created with light.
Percentages of red, green, & blue
light are used to generate color on a
computer screen.http://en.wikipedia.org/wiki/Additive_color
