Hey @Czaki - I've reviewed your changes - here's some feedback:

Overall Comments:

  • Consider the implications of passing default_colors as a parameter. If the same object is reused across multiple calls, it could lead to unexpected behavior. Consider creating a new cycle object within the function to ensure consistent behavior across calls.

710-715: LGTM! Consider adding more test cases.

The test_name_to_rgb function covers the basic functionality of the _name_to_rgb function. It's good that you're testing common colors and the error case.

To improve the test coverage, consider adding the following:

  1. Test case-insensitivity (e.g., "RED", "Blue").
  2. Test for more color names (e.g., "yellow", "cyan", "magenta").
  3. Test for color names with spaces (e.g., "dark green", "light blue").
  4. Test for edge cases like empty string or non-string input.

Here's an example of how you could expand the test:

def test_name_to_rgb():
    assert _name_to_rgb("red") == (255, 0, 0)
    assert _name_to_rgb("blue") == (0, 0, 255)
    assert _name_to_rgb("green") == (0, 255, 0)
    assert _name_to_rgb("YELLOW") == (255, 255, 0)  # Test case-insensitivity
    assert _name_to_rgb("Cyan") == (0, 255, 255)  # Test more colors
    assert _name_to_rgb("magenta") == (255, 0, 255)
    assert _name_to_rgb("dark green") == (0, 100, 0)  # Test color with space
    
    with pytest.raises(ValueError, match="Unknown color name"):
        _name_to_rgb("strange")
    
    with pytest.raises(ValueError, match="Invalid color name"):
        _name_to_rgb("")  # Test empty string
    
    with pytest.raises(TypeError, match="Color name must be a string"):
        _name_to_rgb(123)  # Test non-string input

This expanded test suite will provide more comprehensive coverage of the _name_to_rgb function.

Line range hint 257-288: Improved implementation with list comprehensions and color cycling

The refactoring of the _adjust_channel_info method is well done. The use of list comprehensions and the cycle function from itertools improves code readability and efficiency. The logic for handling missing channel information is preserved while being more concise.

Consider adding a type hint for the default_colors parameter in the method signature to improve code clarity:

def _adjust_channel_info(
    channel_info: list[ChannelInfo | ChannelInfoFull] | None,
    channel_array: list[np.ndarray],
    default_colors: tuple[str, ...] = ("red", "blue", "green", "yellow", "magenta", "cyan"),
) -> list[ChannelInfoFull]:

708-715: Summary: Good addition of color name to RGB conversion functionality.

The changes in this file introduce a new _name_to_rgb function and its corresponding test. This addition complements the existing _hex_to_rgb function, providing more flexibility in color handling for the PartSegImage module. The implementation seems sound, although not visible in the diff.

A few points to consider:

  1. Ensure that the _name_to_rgb function is well-documented with docstrings.
  2. Consider expanding the test cases as suggested earlier to improve coverage.
  3. If this function is intended for public use, consider adding it to the module's public API and documenting it accordingly.

Overall, this is a valuable addition to the color handling capabilities of the module.

253-255: Method signature updated with default colors parameter

The _adjust_channel_info method now includes a default_colors parameter with a default value of common color names. This change enhances the flexibility of the method by allowing customization of default colors.


Line range hint 253-288: Summary: Improved channel info adjustment with flexible color handling

The changes to the _adjust_channel_info method enhance the Image class's functionality by:

  1. Adding a customizable default_colors parameter.
  2. Implementing color cycling for consistent color assignment.
  3. Refactoring the code to use list comprehensions for improved readability and efficiency.

These modifications make the method more flexible and maintainable without introducing any apparent issues. The changes align well with the existing codebase and improve the overall quality of the Image class.

710-723: LGTM: Comprehensive test coverage for _name_to_rgb function

The new test function provides good coverage for the _name_to_rgb function, including:

  • Basic color conversions
  • Case insensitivity
  • Error handling for unknown colors and empty strings

Consider adding a test for a color with non-zero values for all RGB components, such as:

assert _name_to_rgb("purple") == (128, 0, 128)

This would ensure that the function correctly handles colors with mixed RGB values.

Line range hint 253-288: LGTM! Improved readability and efficiency.

The changes to the _adjust_channel_info method are well-implemented. The use of list comprehensions and the cycle function from itertools makes the code more concise and efficient. The addition of the default_colors parameter allows for greater flexibility.

Consider adding type hints for the default_colors parameter:

def _adjust_channel_info(
    channel_info: list[ChannelInfo | ChannelInfoFull] | None,
    channel_array: list[np.ndarray],
-   default_colors=("red", "blue", "green", "yellow", "magenta", "cyan"),
+   default_colors: tuple[str, ...] = ("red", "blue", "green", "yellow", "magenta", "cyan"),
) -> list[ChannelInfoFull]:

997-1012: LGTM! Improved color definition handling.

The changes to the color definition handling are well-implemented:

  1. Attempting to import get_color_dict from vispy.color allows for a more comprehensive color set.
  2. The fallback to a hardcoded dictionary ensures the code works even without vispy installed.
  3. This approach provides a good balance between enhanced functionality and manageable dependencies.

Consider adding a warning when falling back to the hardcoded color dictionary:

try:
    from vispy.color import get_color_dict
except ImportError:  # pragma: no cover
+   import warnings
+   warnings.warn("vispy not installed, falling back to limited color set", ImportWarning)
    _NAMED_COLORS = {
        "red": "#FF0000",
        "green": "#008000",
        "blue": "#0000FF",
        "yellow": "#FFFF00",
        "cyan": "#00FFFF",
        "magenta": "#FF00FF",
        "white": "#FFFFFF",
        "black": "#000000",
        "orange": "#FFA500",
    }
else:
    _NAMED_COLORS = get_color_dict()

This warning would inform users that they're using a limited color set and could consider installing vispy for more options.

991-995: LGTM! Improved robustness.

The changes to the _name_to_rgb function enhance its functionality:

  1. Converting the input to lowercase ensures case-insensitive color name matching.
  2. The updated error message provides more clarity when an unknown color name is encountered.

These modifications make the function more user-friendly and less prone to errors.
