Sage Green, Champagne Pink, and Charcoal make a restrained starting point. Terracotta shifts the combination toward warmer earth colors. Powder Blue adds a cooler note.

No. The term describes a visual style rather than a fixed color family. Muted neutrals, deep shades, and bright accents can all belong in a coherent scheme.
Try Sage Green with Ivory and Champagne Pink. Use Charcoal sparingly when you need a darker element.
Choose Shocking Pink or Neon Blue as an accent, with a quieter background. Compare the Retro Colors collection for a different direction.
