Build a professional-grade color tool
Build a professional-grade color tool with HTML5, CSS3 and JavaScript for designers and developers. Create an intuitive interface with multiple selection methods including eyedropper, color wheel, sliders, and input fields. Implement real-time conversion between color formats (RGB, RGBA, HSL, HSLA, HEX, CMYK) with copy functionality. Add a color palette generator with options for complementary, analogous, triadic, tetradic, and monochromatic schemes. Include a favorites system with named collections and export options. Implement color harmony rules visualization with interactive adjustment. Create a gradient generator supporting linear, radial, and conic gradients with multiple color stops. Add an accessibility checker for WCAG compliance with contrast ratios and colorblindness simulation. Implement one-click copy for CSS, SCSS, and SVG code snippets. Include a color naming algorithm to suggest names for selected colors. Support exporting palettes to various formats (Adobe ASE, JSON, CSS variables, SCSS).
Audits foreground/background color pairs for WCAG 2.x contrast (AA and AAA for normal and large text), reports ratios and pass/fail, and notes color-blindness risks. Use when checking UI palettes, design tokens, or asking "is this gray-on-white readable?". Includes a stdlib Python contrast checker with --self-test.
Performs WCAG compliance audits and accessibility remediation for web applications. Use when: 1) Auditing UI for WCAG 2.1/2.2 compliance 2) Fixing screen reader or keyboard navigation issues 3) Implementing ARIA patterns correctly 4) Reviewing color contrast and visual accessibility 5) Creating accessible forms or interactive components
