From 764ac90e60cb910360c75d8962b294623336d042 Mon Sep 17 00:00:00 2001 From: valknarness Date: Fri, 7 Nov 2025 11:42:55 +0100 Subject: [PATCH] feat: implement accessibility tools and named colors explorer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive accessibility features and color naming: **Color Utilities (lib/utils/color.ts):** - getRelativeLuminance() - WCAG 2.1 luminance calculation - getContrastRatio() - Contrast ratio between two colors - hexToRgb() - Convert hex to RGB - checkWCAGCompliance() - AA/AAA compliance checker - Full WCAG 2.1 specification implementation **New UI Component:** - Badge component - Status indicators - Variants: default, success, warning, destructive, outline - Used for pass/fail indicators - Accessible focus states **Accessibility Pages:** 1. Contrast Checker (/accessibility/contrast) - Dual color pickers (foreground/background) - Real-time contrast ratio calculation - Live text preview with both colors - WCAG 2.1 compliance display: - Level AA: Normal text (4.5:1), Large text (3:1), UI (3:1) - Level AAA: Normal text (7:1), Large text (4.5:1) - Pass/Fail badges for each criterion - Swap colors button - Visual feedback with color-coded results 2. Accessibility Dashboard (/accessibility) - Overview of all accessibility tools - Feature cards with icons - Educational content about WCAG 2.1 - Standards explanation (AA vs AAA) - Links to each tool **Named Colors Page (/names):** - Display all 148 CSS/X11 named colors - Search by name or hex value - Sort options (name, hue) - Responsive grid layout (2-6 columns) - Click to copy color - Color name and hex display - Loading and error states - Empty state for no results - Real-time filtering **Batch Operations Page (/batch):** - Placeholder "Coming Soon" page - Feature preview list - Planned capabilities description - Professional coming soon message **Features Implemented:** - Real WCAG calculations (not approximations) - Live contrast ratio updates - Interactive color swapping - Comprehensive compliance checking - Educational content - Named colors from API - Search and filtering - Responsive layouts **Build Status:** ✅ 11 pages successfully rendering ✅ All TypeScript checks passing ✅ No build errors All major sections now have functional or placeholder pages! Next: Polish, testing, and additional enhancements. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- app/accessibility/contrast/page.tsx | 172 ++++++++++++++++++++++++++++ app/accessibility/page.tsx | 103 +++++++++++++++++ app/batch/page.tsx | 37 ++++++ app/names/page.tsx | 106 +++++++++++++++++ components/ui/badge.tsx | 35 ++++++ lib/utils/color.ts | 57 +++++++++ 6 files changed, 510 insertions(+) create mode 100644 app/accessibility/contrast/page.tsx create mode 100644 app/accessibility/page.tsx create mode 100644 app/batch/page.tsx create mode 100644 app/names/page.tsx create mode 100644 components/ui/badge.tsx create mode 100644 lib/utils/color.ts diff --git a/app/accessibility/contrast/page.tsx b/app/accessibility/contrast/page.tsx new file mode 100644 index 0000000..a70126e --- /dev/null +++ b/app/accessibility/contrast/page.tsx @@ -0,0 +1,172 @@ +'use client'; + +import { useState, useEffect } from 'react'; +import { ColorPicker } from '@/components/color/ColorPicker'; +import { Button } from '@/components/ui/button'; +import { Badge } from '@/components/ui/badge'; +import { getContrastRatio, hexToRgb, checkWCAGCompliance } from '@/lib/utils/color'; +import { ArrowLeftRight, Check, X } from 'lucide-react'; + +export default function ContrastPage() { + const [foreground, setForeground] = useState('#000000'); + const [background, setBackground] = useState('#ffffff'); + const [ratio, setRatio] = useState(null); + const [compliance, setCompliance] = useState(null); + + useEffect(() => { + const fgRgb = hexToRgb(foreground); + const bgRgb = hexToRgb(background); + + if (fgRgb && bgRgb) { + const contrastRatio = getContrastRatio(fgRgb, bgRgb); + setRatio(contrastRatio); + setCompliance(checkWCAGCompliance(contrastRatio)); + } + }, [foreground, background]); + + const swapColors = () => { + const temp = foreground; + setForeground(background); + setBackground(temp); + }; + + const ComplianceItem = ({ + label, + passed, + }: { + label: string; + passed: boolean; + }) => ( +

Batch Operations

+

+ Process multiple colors at once with CSV/JSON upload +

+
+ +
+
+ +

Coming Soon

+

+ Batch operations will allow you to upload CSV or JSON files with multiple colors + and apply transformations to all of them at once. +

+
+

Planned features:

+
    +
  • • Upload CSV/JSON color lists
    • +
  • • Bulk format conversion
    • +
  • • Apply operations to all colors
    • +
  • • Export results in multiple formats
    • +
  • • Progress tracking for large batches
