This document discusses subtractive and additive color mixing. Subtractive color mixing uses pigments and starts with white, with additional colors making it darker until it reaches black. Additive color mixing uses light and starts with black, with additional colors making it lighter until it reaches white. It is used in technology like computers and TVs, where combining red, green, and blue light creates other colors.

1. Colour systems

2. Subtractive colours
When we mix colors 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 becomes black.

3. Subtractive colours
Those colours used in
painting- an example of
the colour system method

4. Additive colours
Red,green and blue are the primary
colours which are usually used in additive
color system.
Additive colours mixing begins
with black and ends with white;
as more colours are added,
the result is lighter and tends to
white

5. ADDITIVE COLOURS
In cartels, computers...we see lots of colours.
We created those colours with the colour
method and light. If we see the red colour in a
picture, it means that there are all colours
except red.
