Over the ages of professional real estate signage has played an important part. Passersby are attracted by signs and people who are looking for the houses can find them easier. People frequently go out on the weekends to look at houses with for sale signs hanging in front of them. While that is happening less and less the real estate sign still holds power and very few companies have changed them over the years.
Coldwell Banker uses a white background sign with a blue logo that is easy to distinguish from most other signs. Over the years little has changed about this sign. A new 3D sign was released not too long ago but only the effect of the design is changed, the core elements remain the same. The only major real estate company that you could confuse a Coldwell Banker sign with is Windermere. Windermere signs also use a white background but the text is also displayed on that white background. What makes it easy to confuse for a Coldwell Banker sign is the blue backgrounded for sale label that runs across the top of the sign.
Sotheby's sign is relatively close to both Coldwell Banker and Windermere's sign but just in the fact that it uses white and blue. The Sotheby's sign is blue with white text. In complete contrast Keller Williams uses an almost completely red background for some of its signs. Depending on the usage of the real estate sign it may also contain a partially white or black background. No other major reality companies use the distinctive red backgrounds but a few smaller ones do.
Century 21 signs have a black background and are the only major real estate company in the United States to do so. The design is finished off with a yellow house logo and white text. A few smaller companies such as Platinum Realty, Reece Nichols, and Semonin Realtors use black signs but they all lack the distinctive yellow house shape.
Each one of these signs you were probably able to recall in your head because chances are you have seen them before. All of these companies have created a brand image that allow someone to instantly identify who is selling a house. Realtors get a sense of authority from their signs, people know who they are and who they work for based off the real estate for sale sign sitting guard in the yard.
