- Screen Pixel Sampling: Click "Pick Color from Screen" to activate your browser's native Eyedropper cursor and sample any pixel color from any open desktop app or browser tab.
- Convert Color Formats: Enter or tweak HEX (`#3b82f6`), RGB (`rgb(59, 130, 246)`), or HSL (`hsl(217, 91%, 60%)`) values to convert color formats instantaneously.
- Extract Image Palettes: Upload any photograph, logo, or UI mockup image to automatically extract a 6-color dominant brand palette.
- Generate Color Harmonies: Explore complementary, analogous, and triadic color schemes with 1-click HEX code copying for CSS stylesheets.

Best Practices for Web Color Design & Accessibility
- Maintain WCAG 2.1 Contrast Standards: Ensure a contrast ratio of at least **4.5:1** for body text and **3.0:1** for large headings to comply with Web Content Accessibility Guidelines (WCAG AA).
- Use 60-30-10 Color Rule: Apply 60% dominant neutral background color, 30% secondary structural color, and 10% vibrant accent color for call-to-action buttons.
- Test Color Blindness Accessibility: Avoid relying solely on red and green indicators for success/error alerts. Use icons and text labels alongside color coding.
