            ## 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.
