Again, it depends upon the purpose of the sign, the color of the building or background it is viewed against, and the style you are trying to convey. Colors can range from bright and even garish for businesses that want to be noticed (i.e., storefronts, night clubs, toy stores), to natural colors such as tan, brown and green (parks, golf courses, cabins),to elegant and rich-looking colors such as metallic gold, dark(royal) blue, bright (royal) red, and white to marine colors like gray, blue, and green. See the photo Galleries for more ideas on colors. In all cases , select colors for text that have good color contrast with the background, so the sign can be easily read.
