Final answer:
The most common color for recreation and services signs is green, as it is visible and used to convey clear, specific information. Designers often use such distinct colors to create logos that are easily identifiable and characterize a company.
Step-by-step explanation:
The color most commonly associated with recreation and services signs is green. This is because green is easy to see and is commonly used to indicate permitted activities or to provide guidance. In terms of graphic design, especially for designers creating logos, the intention is to devise symbols that carry a corporate identity that is readily identifiable, unique, and reflective of the company’s character. Similarly, recreation and services signs aim to convey specific information clearly and unmistakably to those viewing them. Therefore, colors like green or sometimes brown are predominantly employed for parks and recreation signs, to provide information on services available or direct people effectively.
