Good article on colour combinations. The focus here is on web design, but it can be easily applied to print as well. There are six different colour combinations described:
- Split Complementary
Using several tones of a single colour; such as light, medium and dark blue.
Using three consecutive colours from the colour wheel; such as blue, green, lime
Using two complementary colours, which are colours that are opposite each other on the colour wheel; such as violet and orange.
4. Split Complentary
Taking a colour, and the colours either side of the complementary colour; such as yellow with red and blue violet.
Using three colours, equally spaced across the colour wheel; such as blue, lime and red.
Using four colours, equally spaced across the colour wheel; such as red, green, blue violet and orange.
