Terminal control/Coloured text

The task is to display a a word in various colours on the terminal. The system palette, or colours such as Red, Green, Blue, Magenta, Cyan, and Yellow can be used.

Terminal control/Coloured text 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.

Optionally demonstrate:

• How the system should determine if the terminal supports colour
• Setting of the background colour
• How to cause blinking or flashing (if supported by the terminal)
