Document Summary

Colour: colour is used to attract attention, group attention, indicate meaning, and improve aesthetics, you shouldn"t use more than about 5 colours, more colours makes it harder to percieve things. People have varying degrees of colour blindness, so care must be taken in using colours to ensure that meaning is not taken away by accident. Saturated colours draw more attention, unsaturated colours (greyed out) colours do not. People perceive different meaning from different colour schemes: warm and cool colours have different meaning, use complimentary colours, take a look at a colour pallette or colour wheel. Static elements should be aligned such that they would appear to move together if they were in motion. Comparison: a method to illustrate two or more related variables, ensure you are comparing related items, use the same context, relationships, units, etc, graph design to demonstrate effects. Confirmation: requirement for verification of actions before they are performed, example: warning before permanent deletion of files.
