Summary

This PR updates the chat input send button (ghost button) colors to use theme-consistent semantic colors instead of hardcoded gray values that required light/dark theme detection. The changes:

• Replace conditional gray60/gray80/gray40 colors with fadedText40/fadedText60
• Change hover state from primary to bodyText color
• Add new active state that shows primary color
• Remove background color change on focus-visible (keeping focus ring)
• Standardize disabled state color to fadedText40

Code Quality

Positive changes:

1. Better theme consistency (lines 163-167 in styled-components.ts): The new implementation uses fadedText40 and fadedText60, which are derived from bodyText with transparency. This makes the colors automatically adapt to any custom theme's text color, rather than relying on hardcoded gray values.

2. Simplified logic: Removed the hasLightBackgroundColor import and conditional logic for determining colors. The code is now more declarative and easier to maintain.

3. Clearer interaction states (lines 190-195): Added explicit &:active state that shows primary color, providing better user feedback during click interactions.

Minor observations:

• The removal of backgroundColor change on focus-visible (line 188) is acceptable since the boxShadow focus ring (via getPrimaryFocusBoxShadow) is retained, maintaining keyboard accessibility.

• The hover color change from primary to bodyText (line 191) is a design decision that follows the Figma design specification mentioned in the PR.

Test Coverage

E2E Snapshot Tests:

• ✅ Updated snapshots for st_chat_input-column_audio_with_files across multiple browsers and themes:
  • dark_theme-chromium
  • dark_theme-firefox
  • dark_theme-webkit
  • light_theme-firefox

Observations:

• The snapshot tests capture the visual appearance of the chat input with audio and files, which includes the ghost buttons being modified.
• The existing unit tests in ChatInput.test.tsx focus on behavior (keyboard interactions, state management, file uploads) rather than styling, which is appropriate. CSS styling is best verified through visual snapshot tests.
• No new tests are required as the existing snapshot tests adequately cover the visual changes.

Backwards Compatibility

Low Risk:

• This is a pure styling change with no API modifications
• No changes to component props, behavior, or protobuf definitions
• The change actually improves compatibility with custom themes since:
  • fadedText40/fadedText60 are derived from the theme's bodyText color
  • Previously hardcoded gray values (gray60, gray80, gray40) would not adapt to custom themes

Visual Change:

• Users will notice the ghost button hover state now shows bodyText (high contrast) instead of primary (accent color)
• The primary color now appears on click/active state
• This aligns with the Figma design specification shown in the PR

Security & Risk

No security concerns identified:

• Pure CSS styling changes with no logic modifications
• No user input handling changes
• No data flow modifications

Low regression risk:

• The change uses established theme color variables (fadedText40, fadedText60, bodyText, primary) that are already used extensively throughout the codebase
• The getPrimaryFocusBoxShadow helper is retained for accessibility

Recommendations

No blocking issues identified. Minor suggestions:

1. Consider adding light_theme-chromium snapshot (optional): The PR updates light_theme-firefox but not light_theme-chromium. If both are typically updated together, ensure the chromium snapshot is also regenerated. However, this may be expected if there were no visual differences.

2. Documentation (optional): Consider adding a brief comment in the styled-components file explaining the color scheme for ghost buttons (default → hover → active → disabled states) for future maintainers.

Verdict

APPROVED: The PR successfully improves theme consistency by replacing hardcoded gray color logic with semantic theme colors. The changes are well-scoped, follow existing patterns in the codebase, and the visual changes are covered by updated E2E snapshot tests. The removal of hasLightBackgroundColor dependency simplifies the code while making it more adaptable to custom themes.
