#1C1F21 Hex Color
A sophisticated near-black charcoal grey
This near-black grey provides a professional, grounded foundation for dark mode interfaces. Because of its extreme darkness and neutral character, white text remains highly legible against it. The hex code #1c1f21 works best as a primary background color rather than for fine details or typography, which can lose definition against such a deep, muted tone. Pair it with soft, muted accent colors to maintain a sophisticated palette.
