Basic Principles CONTRAST

Contrast is what makes your design interesting.
There are lots of ways to achieve contrast in your work. You can use different shapes and sizes, light and dark or big and small. As well as providing interest, contrast provides emphasis. For example, a splash of colour will attract interest but can also be a way of highlighting an important fact or issue.
If you want to be noticed, you have to stand out in the crowd and be different from the rest. The single black sheep is always more interesting than an entire flock of white sheep.
