Once you have mastered the concept of the color wheel, you have a good framework 
for experimenting with color combinations. Many books targeted at graphic designers 
show groups of preselected color combinations. Some are organized by themes or 
moods, and some are based on a custom color system such as PANTONE. The more 
you develop a critical facility for judging color combinations, the more you will be able 
to trust your own eye for color. The bibliography at the back of this manual includes 
books on design.
Color and text
It is not a coincidence that the overwhelming majority of text you see is printed in 
black on white paper. Text in black on white is highly legible and is not fatiguing to 
read for extended periods. For many color materials, using black text on a white 
background and confining color to graphic elements and headings is a good choice.
Color text can add flair to documents printed on paper when used skillfully. This 
technique is widely used in presentations. When using color text, avoid dazzling text 
and background combinations created from primary complements, especially red and 
cyan or red and blue; they are visually fatiguing and hard to read. Color text is more 
legible when distinguished from its background by a difference in lightness—for 
example, dark blue text on a light beige background. In addition, using many different 
colors in a string of text makes for a confused appearance and is hard to read. However, 
using a single highlight color is an effective way to draw the reader’s eye to selected 
words. See plate 10 for color text samples.
When using color text, keep in mind that small font sizes typically do not print in 
color with the same sharpness as in black. In most applications, black text prints 
exclusively in black toner, while color text usually prints with two or more toners. Any 
misregistration between the different toners on paper causes color text to lose 
definition. You can make test prints to find the smallest point size at which color text 
prints clearly. When using high-end graphics applications that allow you to specify 
color as percentages of cyan, magenta, yellow, and black, you can create pure cyan or 
pure magenta text that prints with the same sharpness as black text. (Pure yellow text is 
extremely hard to read on anything but a dark or complementary background.)
