/*
 * Info: http://www.termsys.demon.co.uk/vtansi.htm#colors 
 * Following caveats
 * bright    - brightens the color (bold-blue is same as brigthtBlue)
 * dim       - nothing on Mac or Linux
 * italic    - nothing on Mac or Linux
 * underline - underlines string
 * blink     - nothing on Mac or linux
 * inverse   - background becomes foreground and vice versa
 *
 * In summary, the only styles that work are:
 *  - bright, underline and inverse
 *  - the others are only included for completeness
