@FraserGreenroyd I would not mind ignoring the compliance taken that it is a minor bugfix that does not interfere with the method signatures at all.

This is not a static method so there shouldn't be a test on it related to extension methods.

@BHoMBot check copyright-compliance
@BHoMBot check dataset-compliance

[bhombot-ci]

@adecler to confirm, the following checks are now queued:

• copyright-compliance
• dataset-compliance

[adecler]

Tested and works fine

• both when Color is a top object and a property
• both on old version and new

Glad to see that the verification on serialization is also happy
