🎨 Customization

Color Scheme

The dark theme uses carefully chosen colors:

bg_dark = '#0a0e14'        # Main background
bg_darker = '#050810'      # Darker elements
accent_green = '#00ff41'   # Matrix green (primary)
accent_cyan = '#00ffff'    # Cyan (highlights)
accent_red = '#ff0055'     # Red (warnings/errors)
button_bg = '#1a1f2e'      # Button background
button_hover = '#2d3548'   # Button hover state

Extending Modules

Add custom modules in modules/ directory:

# modules/custom_module.py

def run(args):
    """Your custom OSINT module"""
    print(f"[*] Running custom scan on {args.target}")
    # Your logic here
    return results
