Light-dark contrast is one of my favourites. It is a contrast in value of colours and is a common way to decorate a room. There are 4 main categories of light-dark contrast:
- In a monochromatic contrast there is one colour in varying tints and shades.
- A polychromatic contrast requires at least two different colours that are also different in value.
- An achromatic contrast is one in which there are only black, white and grey.
- There are also two combinations possible: either achromatic combined with monochromatic or achromatic combined with polychromatic.
