Tips for pairing them
Use gray as the base (walls, sofa, pants) and pink as the secondary or accent color. Light gray with dusty pink feels calm; dark gray with hot pink feels more modern. In fashion, a gray coat with a pink sweater is a safe bet. In design, gray works for text and backgrounds, and pink for details.
Contrast between them: 1.8:1. Don’t put text in one color on the other: it’s hard to read.
