Colour bars/Display

The task is to display a series of colour bars across the width of the display. The colour bars should either utilize the system pallet, or the primary colours and black and white bars should also be included.

Colour bars/Display is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

A typical colour bar sequence would be Black, Red, Green, Blue, Magenta, Cyan, Yellow, White
