Choosing the color or colors on your political campaign sign will make a big difference in whether the sign makes an impact with voters or not, but it’s also important to choose a color that your printer will appreciate too! The two most common color coding systems that you will encounter on the campaign trail are the Pantone Color Matching System (PMS) or 4 color process, which mixes combinations of cyan, magenta, yellow, and black (CMYK) to create other colors.
Especially if you are doing a larger run and omitting expensive and unnecessary options like a image of the candidate, CMYK is the most common of the two. Pantone colors are very specific and they are used to maintain consistency over a broad range of mediums and print jobs, so they are ideal if color matching is essential. Process color, on the other hand, is the most economical option for large runs of most political printing including direct mail and yard signs.
Truth be told your campaign sign printer will be able to handle whatever color matching issue you have, but at a price. It’s best to choose from this palette of colors, so that you know what exact colors that you have on your yard sign. There are hundreds of colors to choose from and this list includes both the PMS number and the CMYK values for you to share with your graphic designer and sign printer.

For a full list of available Pantone colors and RGB Hex values for process colors, there are a number of resources available online including this one. If you find a PMS color or a 4 color process color and need to convert it to one or other to give you graphic designer or printer guidance, there are a number of free color conversion tools available.
