Colored ink can highlight borders, rules or deadlines. It can also be an organizing element used to departmentalize the document or to draw attention to certain areas. Even colored paper can have an effect on the reader, but use color sparingly. Too much color will cause it to loose impact. Color gains impact when used selectively.
Bright colors indicate excitement and subdued colors can add dignity.
Choose the right typeface. Using the sans serif for headlines and the serif for body text is a common and familiar formula. Don't underline text unless absolutely necessary. Avoid text in all-capital letters. Professional typographers use bold and italic type for emphasis within sentences-not underlines.
