+# Accessibility Improvements Update
+
+## Color Contrast Enhancements
+
+We've made several improvements to address readability concerns with the blue background:
+
+1. **Lightened the primary blue color**:
+   - Changed from `#1b365d` (original Ploughshares blue) to `#2d5b96` (lighter shade)
+   - Kept the original as `--ploughshares-dark-blue` for elements that need darker contrast
+   - Added a new `--ploughshares-light-blue: #6b93c3` for even lighter contrast needs
+
+2. **Improved color variable usage**:
+   - Updated all references to use the new color variables consistently
+   - Ensured hover states use appropriate darker variants for visual feedback
+
+3. **Enhanced text contrast**:
+   - Verified all text/background combinations meet WCAG 2.1 AA standards (4.5:1 minimum)
+   - Added explicit `color: white` declarations to all button styles to ensure proper contrast
+
+## Interactive Contrast Checker Tool
+
+Added a new interactive contrast checker tool to help test and verify color combinations:
+
+1. **Features**:
+   - Real-time contrast ratio calculation
+   - WCAG AA and AAA compliance indicators
+   - Color pickers for foreground and background colors
+   - Sample text preview with selected colors
+   - Toggle button in bottom-right corner of every page
+
+2. **Implementation**:
+   - Created `contrast-checker.js` with self-contained functionality
+   - Added to base template so it's available on all pages
+   - Follows WCAG formula for calculating luminance and contrast ratios
+
+3. **Usage**:
+   - Click the "Contrast Checker" button in the bottom right of any page
+   - Select foreground and background colors using the color pickers
+   - View the calculated contrast ratio and compliance status
+   - Test different color combinations for accessibility
+
+## Navigation Improvements
+
+1. **Added Accessibility Page Link**:
+   - Added a direct link to the accessibility testing page in the main navigation
+   - Includes appropriate icon and ARIA attributes
+
+2. **Testing Tools**:
+   - Created `run_lighthouse_test.sh` with instructions for running Lighthouse tests
+   - Updated the accessibility testing page with examples of the new color scheme
+
+## How to Test the Changes
+
+1. **Visit the application** at http://localhost:5005
+2. **Use the contrast checker tool** by clicking the button in the bottom right corner
+3. **Navigate to the Accessibility page** through the main navigation
+4. **Check the color samples** on the accessibility testing page
+5. **Run Lighthouse tests** using the provided script: `./run_lighthouse_test.sh`
+
+These improvements ensure better readability throughout the application while maintaining the Project Ploughshares brand identity.

+# Accessibility Improvements for Project Ploughshares
+
+This document outlines the accessibility improvements made to the Project Ploughshares Transaction Management System to ensure compliance with WCAG 2.1 AA standards.
+
+## Color Contrast Improvements
+
+- Increased text contrast ratios throughout the application:
+  - Default text color changed to `#333333` for better contrast against white backgrounds
+  - Footer text color improved from `#777` to `#555555`
+  - Button text colors explicitly set to ensure contrast with button backgrounds
+  - Table headers use white text on dark blue background with sufficient contrast
+
+- Created a consistent color palette with accessible colors:
+  - Primary blue: `#1b365d` (Ploughshares brand color)
+  - Accent color: `#c4d600` (Ploughshares brand accent)
+  - Success color: `#2e7d32` (Accessible green)
+  - Warning color: `#e65100` (Accessible orange)
+  - Info color: `#0277bd` (Accessible blue)
+  - Error color: `#c62828` (Accessible red)
+
+## Keyboard Navigation
+
+- Added a "Skip to main content" link that appears on keyboard focus
+- Improved focus visibility with a prominent outline on all interactive elements
+- Ensured all interactive elements can be accessed via keyboard
+- Added `aria-current="page"` to indicate the current page in navigation
+
+## Screen Reader Support
+
+- Added appropriate ARIA attributes throughout the application:
+  - `aria-label` for icon-only buttons
+  - `aria-hidden="true"` for decorative icons
+  - `aria-describedby` for form fields with help text
+  - `aria-current` for indicating current page
+  
+- Improved semantic HTML structure:
+  - Proper heading hierarchy (h1, h2, h3, etc.)
+  - Semantic HTML5 elements (header, main, footer, section, etc.)
+  - Table captions and proper scope attributes for table headers
+
+## Text Readability
+
+- Set base font size to 16px for optimal readability
+- Increased line height to 1.5 for better text spacing
+- Ensured links are underlined for better visibility
+- Added sufficient spacing between interactive elements
+
+## Form Accessibility
+
+- All form controls have associated labels
+- Form fields with help text use `aria-describedby`
+- Form validation errors are announced to screen readers
+- Improved focus states for form elements
+
+## Responsive Design
+
+- Ensured the application is usable at all viewport sizes
+- Adjusted text size on smaller screens while maintaining readability
+- Made tables responsive with horizontal scrolling on small screens
+- Ensured touch targets are large enough on mobile devices
+
+## Testing Tools
+
+- Created an accessibility testing page at `/accessibility`
+- Added contrast checking script (`check_contrast.py`)
+- Added Lighthouse accessibility testing script (`check_lighthouse.sh`)
+
+## Additional Improvements
+
+- Added support for high contrast mode with `@media (forced-colors: active)`
+- Improved button and link hover/focus states
+- Added proper width and height attributes to images
+- Replaced Unicode icon characters with Bootstrap Icons for better screen reader compatibility
+
+## How to Test
+
+1. Visit the accessibility testing page at http://localhost:5005/accessibility
+2. Use the keyboard to navigate through all interactive elements
+3. Test with a screen reader (VoiceOver on macOS, NVDA on Windows)
+4. Run the Lighthouse accessibility test using `./check_lighthouse.sh`
+5. Check contrast ratios using `python3 check_contrast.py`
+
+## Future Improvements
+
+- Add ARIA live regions for dynamic content updates
+- Implement more robust form validation with appropriate error messaging
+- Add language attributes for multilingual content
+- Improve keyboard shortcuts for power users
+- Conduct user testing with people who have disabilities
