            ## What is HexaGrid Creator?
            HexaGrid Creator is a web-based application that allows you to apply a hexagon grid overlay to any image. You can customize the size, color, and opacity of the hexagons, as well as the background and border colors. The result is a visually striking image that looks like it was made from hexagonal tiles!

            ### What Can You Do?
            - **Generate Hexagon Grids:** Create beautiful hexagon grid overlays on any image with fully customizable parameters.
            - **AI-Powered Image Generation:** Use advanced AI models to generate images based on your prompts and apply hexagon grids to them.
            - **Color Exclusion:** Select and exclude specific colors from your hexagon grid for a cleaner and more refined look.
            - **Interactive Customization:** Adjust hexagon size, border size, rotation, background color, and more in real-time.
            - **Depth and 3D Model Generation:** Generate depth maps and 3D models from your images for enhanced visualization.
            - **Image Filter [Look-Up Table (LUT)] Application:** Apply filters (LUTs) to your images for color grading and enhancement.
            - **Pre-rendered Maps:** Access a library of pre-rendered hexagon maps for quick and easy customization.
            - **Add Margins:** Add customizable margins around your images for a polished finish.

            ### Why You'll Love It
            - **Fun and Easy to Use:** With an intuitive interface and real-time previews, creating hexagon grids has never been this fun!
            - **Endless Creativity:** Unleash your creativity with endless customization options and see your images transform in unique ways.
            - **Hexagon-Inspired Theme:** Enjoy a delightful yellow and purple theme inspired by hexagons! ⬢
            - **Advanced AI Models:** Leverage advanced AI models and LoRA weights for high-quality image generation and customization.

            ### Get Started
            1. **Upload or Generate an Image:** Start by uploading your own image or generate one using our AI-powered tool.
            2. **Customize Your Grid:** Play around with the settings to create the perfect hexagon grid overlay.
            3. **Download and Share:** Once you're happy with your creation, download it and share it with the world!

            ### Advanced Features
            - **Generative AI Integration:** Utilize models like `black-forest-labs/FLUX.1-dev` and various LoRA weights for generating unique images.
