Book excerpt: Color for Impact deserves to be within reach of every editor and desktop publisher's computer. It encourages newcomers to think about colour in new ways and reminds experienced designers that colour can be a two-edged sword: it can as easily obscure a message as drive it home. In either case, by focusing on the message and the communication, rather than what Jan White calls the "decorative" aspects of colour, Color for Impact will help you to take advantage of the reduced costs and increased availability of colour at all levels. Contents: Getting the Best Out of Colour; Ten Commandments on Using Colour; Where to Use Colour; How Much Colour to Use; Copying Colour in Black-and-White; Making the Most of Colour; Which Colour to Choose; Combining Colours with Colours; Colour and Panels; Colour and Pictures; Colour and Type; How Words, Shape, Space, and Colour Produce Impact; Technicalities About Colour.
