A few rules of thumb
Try some of the following strategies for creating successful color materials:
• Rather than applying colors indiscriminately, use color to aid comprehension. In 
presentations, graphs, and charts, use color to highlight patterns and emphasize 
differences. 
• In general, fewer colors work better than many colors.
• Use red as an accent color. Red is particularly effective when used in otherwise 
monochromatic materials.
• Consider the tastes of your target audience when choosing colors. 
• Keep a file of printed color pieces that appeal to you or strike you as effective. Refer 
to it for ideas when designing your own documents.
Color wheel
A color wheel (plate 8) is a helpful tool for understanding the interrelation of colors. 
The colors on one side of the color wheel, from magenta to yellow, appear to most 
people to be warm colors, while those on the other side, from green to blue, appear to 
be cool. The distance between two colors on the color wheel can help predict how they 
will appear when seen side by side. 
Colors opposite one another on the wheel are called complements (plate 9), and create 
a striking contrast side by side. This can be the basis for a bold graphical design, but it 
is an effect you should use with discretion since it can be visually fatiguing. Other bold 
combinations to consider are split complements (a color and the two colors adjacent to 
its complement) and triads (three colors evenly spaced on the color wheel). Colors 
adjacent to one another on the color wheel result in subtle harmonies.
The color wheel simplifies color relationships for the purpose of clarity, showing only 
saturated or pure colors. Adding the myriad variations of each hue to the palette (more 
or less saturated, darker or lighter) creates a wealth of possibilities. Taking a pair of 
complements from the color wheel and varying the saturation and brightness of one or 
both colors produces a very different result from the pure complements. Combining a 
light tint of a warm color with a darker shade of its cooler complement often gives 
pleasing results. Combining a darker shade of a warm color with a light tint of its 
cooler complement produces an unusual effect you may like.
