Contrast is an essential element in sign legibility. You would think this is a no brainer, but many times we see black and blue or orange and yellow sign along the side of the road, what was the message? No idea!! When selecting colors, we suggest you use one very dark color and one very light color. For example, use black, red, blue or brown on a white background, use yellow on a black background, and use white on a blue, green or red background. Also keep in mind that many people are color blind, avoid similar colors like blue and green or yellow and green. If you have two similar colors that you want or need to use, consider adding an outline or shadow to provide the contrast and visibility. Lastly, When designing, remember to utilize the color of the material you will be using and let it help you be effective in getting your message out.
