It can be described as pale, delicate, faded and unsaturated.
Set in black, because black reads best on it.
A nature trail is a specially developed hiking trail or footpath that runs through the countryside, along which there are marked stations or stops next to points of natural, technological or cultural interest. These may convey information about, for example, flora and fauna, soil science, geology, mining, ecology or cultural history. Longer trails that link more widely spaced natural phenomena or structures together may be referred to as themed trails or paths.
Read on WikipediaNature, in the broadest sense, is the physical world or universe. In this general sense nature refers to the laws, elements and phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright separate and even superior to nature.
Read on WikipediaA trail, also known as a path or track, is a dirt road or a small paved road, usually through an undeveloped natural area, that is designed primarily for use by pedestrians, equestrians and non-motorized vehicles, although occasionally some off-roading motor vehicles may also use it. In the United Kingdom and Ireland, footpath or hiking trail is the preferred term. However, it is sometimes applied to highways in North America. In the United States, the term was historically used to describe the westward expansion trails, which are land routes into or through wildness regions of the American West used by explorers and migrants.
