Campaign Yard Sign Substrate – Corrugated Plastic

Corrugated plastic is created by bonding two flat polymer sheets with plastic flutes in between. It looks like corrugated cardboard and comes in a variety of colors. The tubes make the material rigid but also lightweight. Corrugated plastic is often referred to by brand names particularly Coroplast but also IntePro, Correx, Twinplast, Corriflute, or Corflute. It is also known as corriboard or twinfall plastic.

The most important qualities of the substrate as campaign lawn signs include rigidity, easily cleanable, and print quality characteristics that allow for anything a simple single color to a digital image. While the rigidity maintains the shape of the yard sign much better than a poly bag sign, it also makes the lawn sign more susceptible to the wind. These lawn signs can blow away in the wind in the most extreme cases. The rigidity of these yard signs allows campaigns to use them to other purposes such as rally signs or for visibility.

The smooth plastic surface and the rigidity lend themselves to easy cleaning. If a yard sign has been on a lawn for a long time, the sign will accumulate dust and dirt. Corrugated plastic signs can be wiped clean with a wet towel. This sign substrate will also withstand chemical cleaners if needed.

The greatest benefit to choosing this substrate is the ability to shape it however the campaign would like their sign to look. With a fold over sign or poly bag sign, your limited to a standard rectangular shape, but with corrugated plastic there are a variety of options. Some candidates have shaped their coroplast signs like their state or district while others have used shapes that help identify who they are what they are running for such as a sheriff’s badge or an apple indicating the candidate was a teacher.

Printing on corrugated plastic has its challenges. Coroplast is sensitive to the type of ink and its application to cure properly. It is important to use a printer that has experienced with corrugated plastic because applying too much ink or ink that is too thick will not adhere properly to the yard sign.

Other popular substrates for lawn signs are poly bag and polycoated paperboard, also called fold over signs. Take some time to consider all three types of lawn signs before deciding on which is best for your campaign. Coroplast is often a great choice for a campaign lawn sign.

Campaign Yard Signs and Color Psychology

There is a lot of popular interest in color psychology, but it’s also important to put it in perspective. The colors that the campaign would like to choose from a psychological perspective may not contrast with one another. In this case, it’s best to give priority to choosing colors that contrast and are therefore more easily seen by drivers passing by the campaign yard sign.

Moreover, there are different views on how much impact color has on people. Certain people are more influenced by color than others and depending upon someone’s mood and their basic personality their emotional response to color will be different than someone with a different personality or who is feeling differently.

The Color Psychology of Black

As a backdrop to the text of a sign, black can come across as dark and menacing. Black is rarely used as a background color on political lawn signs partly because of the negative feel to it. The positive association with black that’s most important to yard signs is power and authority. In addition to being a traditional color for text, black is a great choice as text particularly indicating the candidate but also the office sought because it symbolizes authority.

The Color Psychology of White

White reflects all light and can therefore create a sense of space drawing the eye to the copy on the candidate’s yard sign. On the other hand, particularly paired with black, white can feel sterile. To reduce printing costs, white is often the choice for text with a darker color outlining the candidate’s name and the office he or she is seeking. This creates a less expensive, one color lawn sign with a strong contrast between the background and text, which will more than compensate for the mild detrimental psychological effect.

The Color Psychology of Red

Unless there aren’t many other candidates on the ballot, it is often best to avoid red along with blue to differentiate a political campaign’s yard sign from the host of red, white and blue lawn signs from other candidates. With that said, when there isn’t a glut of candidate yard signs, red is a good color choice. It’s associated with love, warmth and comfort. It’s also associated with power as in the “power tie.” Finally, red is associated with the Republican Party and thus conservatism more generally.

The Color Psychology of Blue

While blue is associated with calmness and peace, this is generally a secondary consideration to white being a favorite color of many men and that it is a symbol of the Democratic Party. As mentioned, avoid red, white and blue when there are a number of candidates on the ballot to differentiate the political campaign signs from other candidate’s signs. If that isn’t the case, Democrats should consider this color since it is connected with party. Also, candidates who poll weaker with men could consider using blue on their yard signs since it will appeal to them.

The Color Psychology of Green

Green is a symbol of the natural world. This is a great color for a candidate that has made environmental issues an important part of the campaign. For a one color sign, using a dark green background and white letters presents a sharp, professional look inexpensively while communicating the importance of environmental issues to the candidate. Unlike some more subtle elements of color psychology with other colors, many voters will make the connection between a green yard sign and the environment as they will with a blue sign for a Democrat and red one for a Republican candidate.

The Color Psychology of Yellow

Yellow is the most visible color. It is bright and cheery. Because of these qualities it draws attention unlike any other color. It is a great choice for campaign yard signs particularly as a background with black text. Yellow, however, works well in combination with a number of other colors including brown, purple, blue and green.

The Color Psychology of Purple

If you are a populist candidate or otherwise want to come across as connected with the people of the district, this is a color to avoid as it indicates royalty and wealth. On the other hand, purple also indicates wisdom and spirituality. In a particularly religious district or one with a high population of academics, this color would work psychologically particularly if there are strong lower-case r republican leaning or a significant number of elitist voters.

The Color Psychology of Brown

Brown is a natural color and it gives people a sense of strength and reliability. While it doesn’t convey authority as strong as black, brown’s connection to nature and reliability are important for some campaigns. It is both a good alternative to black as a text color but is also a good choice for a background color. Brown isn’t often used in campaign materials and using it on a political lawn sign is a good opportunity to stand out from other yard signs while conveying a sense of strength and reliability.

The Color Psychology of Orange

Orange is an exciting color. It is part of the family of warm colors as well. Like yellow, orange is an attention getting color. Because it will draw the attention of voters driving by, orange is a great color to use on a yard sign. Because orange conveys excitement, a orange sign will subtly convey to voters that the political campaign is dynamic and has momentum.


For campaigns that want everything to be just so, factor in some of the concepts behind color psychology into the campaign’s yard signs. One of the best times to brainstorm what colors are best for lawn signs is during a general conversation about the color scheme for the campaign website, direct mail and other aspects of the campaign. This way, the campaign isn’t reinventing the wheel discussing colors options for every project and can choose colors that complement each area of the campaign.

Campaign Yard Signs – Are Red, White and Blue the Best Color Options?

Standing Out From the Crowd

The most important consideration when choosing colors for a campaign sign is to choose colors that contrast so that voters are drawn to the sign. Also, be sure to choose colors and a design that makes the text easily readable. Choosing a red, white and blue color scheme is usually readable if the text is of an appropriate size and font, but the sign will get lost the in the crowd.

While the sign will look professional, it won’t get attention both because it will look similar to other candidates’ patriotic-looking yard signs and there are other colors options that grab voters’ attention better. Take a look at bandit signs from small businesses on the side of the road. Many of these signs are yellow and black since that is the best pair of colors to get a person’s attention. Political campaigns can use yellow, orange and other colors that are better suited for getting voters’ attention to leverage the value of the candidate’s lawn sign.

Color Psychology of Red, White and Blue

When there are only a few candidates on the ballot and political campaigns’ aren’t competing against many others for voters to read their yard signs, red is a good color choice. Red is associated with power as in the “power tie.” This strong color presents a candidate as authoritative. Finally, red is associated with the Republican Party and conservatism more generally.

White creates a sense of space on a yard sign. On the other hand, particularly paired with black, white can feel sterile. To reduce printing costs, political campaigns often choose to order one color signs. To do so, campaigns use a dark color to outline the words on the sign creating white lettering. While white might not be the best color from a psychological perspective, the cost savings of using one spot color will more than make up for the negative effects.

Most importantly for Democratic candidates, blue is associated with the Democratic Party and Liberal values. Blue is also associated with calm and peace. It’s also the favorite color of most men. Republican candidates should avoid blue as the predominant color in their campaign lawn signs but blue is a good choice for Democrats.


While red, white and blue are our nations colors and it’s understandable that candidates would want to display their patriotism by using these colors on political lawn signs, they are ordinarily not the best option. There are cases when there are few candidates on the ballot that they will work but these colors still aren’t the best possible option. Political campaigns are best to choose contrasting colors. Choose a color that reflects a lot of light and couple it with a color that makes the copy on the yard sign easily read from the road.
