Automatically adjusts text color for optimal readability:
- Bright backgrounds: Text switches to dark color (#1a1a1a)
- Dark backgrounds: Text remains white (#ffffff)
- Uses luminance formula (0.299×R + 0.587×G + 0.114×B) for accurate brightness detection
- Analyzes images using canvas to sample 100x100 pixels
- Smooth color transitions (0.5s) between background changes
- Adjusts text shadows for better contrast in each mode
- Event time color adapts (#0066cc for light, #4a9eff for dark)
Technical implementation:
- Added calculateImageBrightness() function in app.js
- Modified updateBackground() to analyze and apply appropriate CSS class
- Added .light-bg and .dark-bg CSS classes for text color themes
- Brightness threshold set at 140 (out of 255)
