Tips for pairing them
Use gray as the base and yellow as the accent, in a 70-20-10 split with white. At home, a gray sofa with yellow or mustard pillows is a safe bet. In fashion, a gray coat with a yellow scarf adds a pop of color. In design, yellow buttons stand out on dark gray.
Contrast between them: 2.9:1. Don’t put text in one color on the other: it’s hard to read.
