Colour Theory

If you understand the theory of colours you are better placed to choose the right colour for the right job
When presenting a design or an idea your choice of colours is very important. Many surveys have been carried out on the general public to find out what people like. The findings suggest that very young children like bright, vibrant colours (reds, yellows and oranges etc...) whilst older people like more gentle or sophisticated colours and tones such as shades of blue. It is very important for a designer to understand the way colours are put together/created as this may help in the selection of the right colour scheme for a particular age group. Next time you pass a poster look closely at the colours - the designer has considered them very carefully.

The Colour Wheel

Primary Colours: 

These are colours that cannot be created through the mixing of other colours. They are colours in their own right.

The three primary colours are RED - YELLOW - BLUE.

Primary colours can be mixed together to produce SECONDARY COLOURS. 

Secondary Colours:

The table below shows the combination required to produce secondary colours.

YELLOW + BLUE = GREEN
BLUE + RED = PURPLE
RED + YELLOW = ORANGE

The colour wheel can be seen above and this can be used to help remember primary and secondary colours. The secondary colours are in between the primary colours - for example - between red and blue is purple. Quite simply, mixing the primary colours of red and blue paint together will produce the secondary colour purple.

An important rule of the colour wheel is that colours opposite to each other on the colour wheel usually work well together as a colour scheme. These are known as COMPLEMENTARY COLOURS. Complimentary colours are often used together in graphic design as they tend to give the image/graphic a sense of balance and are visually more aesthetic.


Colours, Feelings, Emotions & Atmosphere:

Designers have a large range of colours at their disposal and most are well aware that certain colours are associated with feelings and emotions. The diagram below show a number of popular colours and the feelings/emotions to which they are associated. Designers, companies and manufacturers use colours cleverly to promote a certain feeling about their products.

Colour Associations

Colours also have an effect on your visitors before they begin to read the content of your web site or printed design. Thus, it is very important for you to consider your target audience, the psychology of color, and the corporate image you wish to project BEFORE you complete your design.

When colour is used correctly, it can add impact and clarity to your message and highlight important points. Alternatively When colour is used incorrectly, it can compromise your message and confuse your target audience.

Colour can work for your web site and printed materials in various ways:
  • Colour emphasizes, highlights, and leads the eye to important points or links.
  • Colour identifies recurring themes (i.e. titles and subtitles are usually the same colours).
  • Conversely, colour can differentiate, such as different colours in pie charts and bar graphs.
  • Colour symbolizes and triggers emotions and associations.

The interpretation of a colour depends on culture, profession, and personal preference. In general, the colours red, orange, and yellow are "exciting" colours and the colors purple, blue, and green are "calming" colours.

Interpretation of colour is not always a matter of personal preference. For example, in Western cultures the colour white symbolizes purity; however, in China the colour white symbolizes death.

To summarise, it is very important to consider your target audience, the psychology of colour, and the image you wish to project before you construct your web-site, printed materials, and logo.
