Review

1. Logic Change:
   o Old Code: The old code sets _name and _color to null unconditionally after adding the line.
   o New Code: The new code sets _name and _color to null only if they are empty or null, otherwise, it retains their values.
2. Code Cleanliness and Readability:
   o The new code introduces a conditional check using String.IsNullOrEmpty, which can make the intent of the code clearer by ensuring that the values are only set to null if they are empty.
   Improvements Needed
3. Code Clarity:
   o Consider adding comments to explain the logic behind the conditional check. This will help future developers understand the reasoning behind this change.
   o Ensure the variable names _name and _color are descriptive enough. If not, consider renaming them for better readability.
4. Performance:
   o Evaluate if the conditional check introduces any performance overhead. If _name and _color are expected to be non-empty most of the time, this overhead should be minimal.
5. Consistency:
   o Ensure that similar conditional checks are applied consistently throughout the codebase where applicable.
6. Testing:
   o Perform thorough testing to ensure that the new logic works as expected in all scenarios. This includes checking cases where _name and _color are both non-empty, empty, and null.
   Summary
   The new code introduces a conditional check to set _name and _color to null only if they are empty. This improves the logic by retaining their values when they are not empty, which might be necessary for subsequent operations. Ensure that this change is well-documented, consistently applied, and thoroughly tested to maintain code quality.
