When you create web pages, aim for a unified tone, look and feel throughout your site. Aim for the right tone to suit your audience group and your subject matter. Keep the tone of your website unrelentingly positive. Use multi-media cautiously – it should enhance the page, not distract the user.  Develop an appropriate identifying brand if you do not already have one, and include it on every page and communication. Color, images and the ‘tone’ of your conversation with the user all help to create a psychological impact on  your users, and help to communicate a subtle message about who you are.
