- Meanings and associations of colour.
- Combinations, secondary tertiary split complimentary etc, + the colour wheel.
- Science of colour, electromagnetic waves and all that.
The article is mainly about the meanings of colours but they have included a couple of extra colours than what I had decided were the main colours. I had:
Red
Orange
Yellow
Green
Blue
Purple
Pink
Brown
Grey
White
Black
But they have also written about
Ivory / Cream
and not included pink (which I only included because my sister told me to)
