Successfully consolidated all color mappings into constants. **What was changed:** 1. **tui/constants.py** - Added four color constant dictionaries: - STATUS_COLORS (issue statuses: triage, todo, in-progress, blocked, in-review, done, archived) - PRIORITY_COLORS (issue priorities: low, medium, high, urgent) - PROJECT_STATUS_COLORS (project statuses: triage, active, on-hold, complete, archived) - MILESTONE_STATUS_COLORS (milestone statuses: planned, in-progress, complete, archived) 2. **tui/formatting.py** - Added colorize_text(text, color) helper function: - Simple wrapper around Text(text, style=color) - Imported all four color constants 3. **tui/app.py** - Refactored colorize methods to use constants: - _colorize_priority(): Removed inline dict, now uses PRIORITY_COLORS - _colorize_issue_status(): Removed inline dict, now uses STATUS_COLORS - _colorize_project_status(): Removed inline dict, now uses PROJECT_STATUS_COLORS - _colorize_milestone_status(): Removed inline dict, now uses MILESTONE_STATUS_COLORS - All methods now use colorize_text() helper 4. **tui/screens/edit.py** - Removed duplicate inline dictionaries: - IssueEditScreen: Status and priority RadioButton colors now use STATUS_COLORS and PRIORITY_COLORS - ProjectEditScreen: Status RadioButton colors now use PROJECT_STATUS_COLORS - MilestoneEditScreen: Status RadioButton colors now use MILESTONE_STATUS_COLORS **Test results:** All 832 tests passed with no failures. **Impact:** - Reduced code by ~100 lines (68 deletions, 65 additions = net -3, but consolidated from multiple duplicates) - Eliminated duplicate color definitions across 3 files - Single source of truth for all color mappings - Easier to maintain and update colors consistently **Commit:** cb8ca93 (feature branch), e796874 (merged to master)
