A neutral color has limited warmth or coolness and little chromatic emphasis. In interface design, black, white, or gray can simplify a busy composition and help it feel harmonious. section 9.2.1
Neutral colors also give stronger colors room to lead. In a complementary scheme, use a neutral alongside the two opposing colors, then let one color dominate and the other act as an accent. section 9.2.1
A calmer interface with focused contrast
A notification badge can remain relatively unobtrusive against a neutral interface while a complementary accent draws attention to it. Black can also create an elevated, high-end feel and produce dynamic contrast beside lighter colors. section 9.2.1 section 9.3
Use neutral color when you need to:
- Simplify a design whose content already feels busy. section 9.2.1
- Support bold complementary colors without letting every color compete equally. section 9.2.1
- Create a clean, elegant, or high-end impression with black. section 9.3
