Trade Secret is a cool grey.
It can be described as cool, muted, greyish and dusty.

A trade secret is a type of intellectual property that protects a formula, process, or other business information that is valuable because it is not generally known or readily ascertainable and that the owner keeps secret in order to maintain a competitive advantage. Well-known examples of trade secrets include the formula for Coca-Cola, the recipe for Kentucky Fried Chicken, and the formula for Zildjian bronze cymbals.
