**Detailed Functionalities**

* **Multi-Format Color Conversion:**
Instantly converts color values across primary web formats in real time: HEX, RGB, HSL, OKLCH, CMYK, and RGBA. Changing any value automatically synchronizes all other format representations.
* **CSS Filter Generator:**
Calculates precise CSS `filter` combinations (`brightness`, `contrast`, `hue-rotate`, `saturate`, `sepia`) required to adapt black or solid-color SVG icons and images to match your selected target color.
* **10-Step Shade Strip Generator:**
Automatically builds a 10-step gradient palette for any selected base color, giving you instant access to lighter tint and darker shade variations for UI state design (hover, focus, active states).
* **Quick Base Color Presets:**
Includes a built-in palette of fundamental base colors for quick one-click color initialization and testing.
* **Alpha Channel & Opacity Control:**
Features a dedicated precision slider to adjust alpha opacity levels with instant live preview in both HEX (8-digit) and RGBA/HSLA formats.
* **One-Click Clipboard & Eyedropper Integration:**
Supports the native system color picker (eyedropper), direct input pasting, and one-click copying for all color code formats with instant toast notifications confirming your action.
* **Adaptive UI & Multi-Language Support:**
Fully responsive UI that automatically matches your operating system's light or dark theme (`prefers-color-scheme`) and supports multi-language localization (English and Ukrainian) based on your browser settings.
