Minimalist professional logo design for a modern creative studio called Empat Ruas. The concept represents the duality of openness and protection through a structured geometric composition. The mark is formed by four balanced elements: two sides open and inviting, two sides closed and protective, creating a symmetrical frame that surrounds a central negative space. The structure resembles a refined abstract doorway or corridor leading inward, where the empty center becomes the primary focal point, symbolizing awareness, presence, and intentional space. Design language should feel calm, intelligent, and editorial—like a contemporary design or film production identity. The emotional tone is subtle and restrained, not decorative or illustrative, but deeply conceptual through spatial composition. Style direction: clean vector geometry, precise alignment, grid-based construction, high-end minimalist branding. The form should feel timeless, sophisticated, and scalable across identity systems. Not too rectangular. No text, no typography, no gradients, no shadows, no 3D effects. Strict monochrome palette (black and white). Strong silhouette clarity at small sizes. The final output should feel like a real-world studio logo used in film, architecture, or premium creative branding.
