Modern Icon Logo Design for IdeasBunker

IdeasBunker is an AI assisted idea creation and planning platform.

I need a clean, modern logo built around a stand-alone icon or symbol—no text lock-ups or combination marks.
- The colour palette is fixed: primary teal #14b8a6, secondary indigo #6366f1, and an accent of amber #fbbf24. Pleaes refrain from using gradients. SOLID COLOURS PREFERED.
- Iconography: (in order) Light bulb, bunker (military), cloud, key hole, nodes. NO brain or systems icongraphy.
- The design should feel fresh and contemporary, work well in flat colour (NO GRADIENTS), and remain recognisable at everything from favicons to large signage.

Deliverables
• Three distinct icon concepts presented in vector format
• One fully refined logo, supplied as AI, SVG, PDF, and transparent-PNG files
• Monochrome and inverted variants for dark or light backgrounds

Let me know how you’ll balance the three colours and craft an icon that carries the brand on its own. A quick note on your creative process and links to similar work will help me choose the right designer.
