Typically, red, white, and black or a combination of those three will get the most attention. If your business is in an area that already has an abundance of signs with those colors then you will want to try something a little different. Take a drive around the area that your business is in and see which signs grab your attention first. Step into the shoes of your potential customers and use the colors that would get your attention if you were driving by.
If you are trying to create a sense of urgency with your sign, then use red!
