For all ambient world print work use the Arial font. You may use all of the fonts out of the font family, including regular, bold, italic and italic bold, where appropriate.
Fonts must be coloured black or white depending on the background colour you are working on. Ensure that the font can be easily read and that there is good contrast between the font colour and the background.
For emails and other online communications also use the Arial font. Again, use black for font or white when placing onto a dark background. Ensure that the font can be easily read on screen.
It is generally accepted that white text on a dark background is hard to read, so use sparingly. Please see the example to the right which demonstrates this.
