Standard and portable approach to set the text and background colors on the console. This function memorizes one previous text and background color (and not more) and can be recalled with color name 'previous'.

OS differences
- The background color may either fill up parts of the rows where text is printed out, or the entire row.
- In some consoles, the color specified as 'default' may deviate from the originally visible colors. This is sometimes the case if a console is started with a background color other than black.
