Color is an important part of the anatomy of a street sign, and you can tell a lot about the meaning of a sign just by looking at its colors. In some cases, the color of a street sign might be more important than the actual message on the sign. For example, if you were to see a red sign near the end of a roadway before an intersection, you know that it's likely either a stop sign or a yield sign without even reading the sign or noticing the shape. This is why it's so important that colors are used appropriately on street signs.
