Colour Theory
Complementary colours are colour opposing colour that cancel each other out and have the highest contrast when placed beside each other. These colours are good for creating high contrast as the opposing colour making a vibrant look that is eye catching.
Split complementary colours consist of three colours, the first is the main colour, and the other two are the colours adjacent of its complementary colour. These colours have good contrast and work well together, they are less harsh that complementary as the lower contrast takes away some of the tension.
Double split complementary colours are colours that are adjacent on both sides of two complementary colours, this creates two complimentary pairs. These colours work best with one colour dominating and with a good balance between warm and cool colours.
Triadic palettes are three colours that are equally space in a triangle on the colour wheel. These colours are most of the time vibrant and work best with one colour dominating and the other two been used to assist.
Analogous colours are three colours that side in a row on the colour wheel. These colours will create a comfortable design; they have a more nature look and will be pleasant to the eyes. When using these make sure to have high enough contrast between the chosen colours.
Monochromatic palettes is using one colour is different shades, so it can range from a darker tone to a pale tone of the chosen colour. A greyscale image is classed as monochromatic as it uses black as the hue and white as the base.
Warm colours are colours that are associated with warmer feeling and other heat associated factors. Reds and yellow are example of theses as they are associated with fire, heat and warm temperature.
Cool colours are colours that are associated with calmer feeling and other relaxed and neutral environments. Blue and green are examples of these are associated with ice, water, sky and cool temperatures
