How can I translate color theory into a warm, cohesive bookstore brand?

[IsabellaNR]

I'm rebranding my small independent bookstore, and I'm completely stuck on choosing a new color palette for the logo and interior. I want the colors to feel warm, inviting, and intellectual, but every combination I try either looks too childish, too corporate, or just clashes. I've been reading about color theory, specifically the psychological impact of different hues, but applying it practically is overwhelming. How do designers translate those principles into a cohesive brand identity that resonates emotionally?
