## Manual Testing Steps

1. **Start visualization server**:
   ```bash
   mcp-vector-search visualize
   ```

2. **Check linear layout**:
   - [ ] Open http://localhost:8765 in browser
   - [ ] Verify all directory/file labels are light gray and readable
   - [ ] Expand a file to show chunks
   - [ ] Verify chunk labels are light purple and readable

3. **Check circular layout**:
   - [ ] Click "Switch to Circular" button
   - [ ] Verify all directory/file labels are light gray and readable
   - [ ] Expand a file to show chunks
   - [ ] Verify chunk labels are light purple and readable

4. **Test different screen conditions**:
   - [ ] Check in bright ambient light
   - [ ] Check in dark ambient light
   - [ ] Check with browser zoom at 80%, 100%, 120%
   - [ ] Check text remains readable when zoomed in/out

## Expected Results

**Before Fix**:

- ❌ Dark purple chunk labels hard to read

**After Fix**:
- ✅ Light gray text clearly visible
