Color scheme changes: - White (#ffffff): Unmodified writeable buffer - Green (#64aa0f): Modified writeable buffer (unsaved changes) - Red (#f06a3f): Read-only buffer - Gold (#c48702): Overwrite mode active Previously: All writeable buffers were green regardless of modification Now: White when clean, green when dirty (better visual feedback) Implementation: - Updated cj/buffer-status-colors in user-constants.el: - Changed 'normal' → 'unmodified' (white) - Added new 'modified' state (green) - Updated state detection in modeline-config.el: - Now checks (buffer-modified-p) before defaulting to unmodified - Updated cursor color logic in ui-config.el: - Same state detection as modeline for consistency - Added after-change-functions hook for real-time updates - Added after-save-hook to update on save Priority order (highest to lowest): 1. Read-only (red) - takes precedence over everything 2. Overwrite mode (gold) - takes precedence over modified state 3. Modified (green) - buffer has unsaved changes 4. Unmodified (white) - default for clean writeable buffers Tests: - 18 comprehensive tests in test-ui-buffer-status-colors.el - Tests state detection logic and priority order - Tests color constant definitions and mappings - Tests integration with cursor and modeline - All tests passing
