General guidelines■Keep a document or design simple and consistent.
■Select colors that look good together and that reinforce your message.
■Check your application for standard palettes to get you started.
■Use a color scheme of five or six shades, and in a series of images, use
the colors in a consistent manner throughout the series.
■Use color to show relationships between objects, such as a range of
values. Objects with a similar meaning or value should be in similar colors.
■Avoid red and green combinations; these colors are hard for people with
red/green color blindness to distinguish.
■Avoid red and blue combinations; these colors cause the eye to focus at
different lengths.
