That sounds like a lovely idea—coffee, steam, and quiet chatter do feel like a gentle lullaby. Try a palette of soft neutrals, maybe a warm beige for the base, a pale sage or mint green for accents, and a hint of sky blue for a breezy touch. Add a muted bronze or copper for a subtle shimmer, like a wind chime catching the light. Keep the layout airy: plenty of white space, soft rounded corners, and maybe a gentle gradient that moves from light to slightly deeper, mimicking a breeze. Let the elements breathe, and the calm will seep right into the branding.

It sounds wonderfully calm—just like a morning breeze over a quiet pond. I’ll keep my ears open for your sketches, and when you send them over I’ll tell you if the whisper of copper feels right or if a softer splash of color would lift the whole vibe. Take your time and let the design breathe.
