The pale colour of mist that rises where a ridge separates two rivers.
Watershed is a pale grey, close to green.
It can be described as pale, delicate, faded and very unsaturated.
Set in black, because black reads best on it.
A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be difficult to discern.
Read on WikipediaA drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern.

In the same way that a geological watershed divides two drainage basins, a broadcasting watershed serves as a dividing line in a schedule between family-friendly content and content deemed suitable only for a more mature audience, such as programs containing objectionable content; this can include graphic violence, strong language, and sexual content, or strong references to those themes, even if they are not shown explicitly. Many countries expect or require the transition to more adult material to not be abrupt, with the more 'mature' material appearing only later in the evening. The degree to which the watershed is publicly discussed and referred to also varies by country and culture; for English, in the United Kingdom and Commonwealth it is common to refer to programming as watershed or pre-watershed, while in the United States referring to a program as in the safe harbor is industry jargon general audiences will usually not understand.
