Color combinations ranked in order of optimum legibility

• Typefaces need to be easily legible and fit your particular busine 
  
  

• White space is important to any graphic. Too much clutter is distracting to potential customers. The industry guideline is 30%-40% of the sign should be blank space.
• Remember some people are color blind. Blue and yellow are easy for color blind people, whereas blue/green or aqua on white backgrounds are difficult for color blind people to read.
• Motorists only have seconds to read your sign and some experts suggest text should only be 3 to 5 words in length. Only popular abbreviations should be used and whenever possible, text should be arranged horizontally instead of vertically.
• Something as simple as borders on a sign dramatically improve the effectiveness of your sign. One study found viewers can comprehend a sign with a border 26% faster than a sign without one.
