From 7341f55dfce5293f5caac2a3c6f83ceaf95b9f77 Mon Sep 17 00:00:00 2001 From: jom-sq <148157197+jom-sq@users.noreply.github.com> Date: Mon, 3 Nov 2025 10:22:31 -0500 Subject: [PATCH] feat(ui): add custom accent color theme support Add comprehensive custom color theming system that allows users to select a custom accent color that works with both light and dark modes. Features: - Custom color picker with preset colors and hex input - Color utility functions for palette generation - Automatic theme color generation from base color - Support for both light and dark modes with custom accent - Persistent theme preferences via localStorage - Initial theme loading to prevent flash of unstyled content Components: - CustomColorPicker: UI for selecting custom colors - ThemeSelector: Enhanced theme selection with custom color toggle - colorUtils: Comprehensive color manipulation utilities Testing: - Added unit tests for color utilities (50+ test cases) - Added component tests for CustomColorPicker (25+ test cases) - Added component tests for ThemeSelector (20+ test cases) - All tests follow best practices with proper mocking and accessibility checks The implementation follows React best practices with: - Named exports for better tree-shaking - Proper TypeScript typing - Accessibility attributes (ARIA labels, roles) - Clean component composition - Utility function extraction for reusability Signed-off-by: jom-sq <148157197+jom-sq@users.noreply.github.com> --- ui/desktop/index.html | 83 ++++ .../GooseSidebar/CustomColorPicker.tsx | 125 ++++++ .../components/GooseSidebar/ThemeSelector.tsx | 211 ++++++---- .../__tests__/CustomColorPicker.test.tsx | 255 ++++++++++++ .../__tests__/ThemeSelector.test.tsx | 377 ++++++++++++++++++ .../settings/app/AppSettingsSection.tsx | 2 +- .../src/utils/__tests__/colorUtils.test.ts | 353 ++++++++++++++++ ui/desktop/src/utils/colorUtils.ts | 317 +++++++++++++++ 8 files changed, 1636 insertions(+), 87 deletions(-) create mode 100644 ui/desktop/src/components/GooseSidebar/CustomColorPicker.tsx create mode 100644 ui/desktop/src/components/GooseSidebar/__tests__/CustomColorPicker.test.tsx create mode 100644 ui/desktop/src/components/GooseSidebar/__tests__/ThemeSelector.test.tsx create mode 100644 ui/desktop/src/utils/__tests__/colorUtils.test.ts create mode 100644 ui/desktop/src/utils/colorUtils.ts diff --git a/ui/desktop/index.html b/ui/desktop/index.html index 32e2a9dbc5..2f03d59269 100644 --- a/ui/desktop/index.html +++ b/ui/desktop/index.html @@ -13,6 +13,7 @@ const useSystemTheme = localStorage.getItem('use_system_theme') === 'true'; const systemPrefersDark = window.matchMedia('(prefers-color-scheme: dark)').matches; const savedTheme = localStorage.getItem('theme'); + const isDark = useSystemTheme ?
