This is a more natural representation than int that allows removal of casts in many places that require uint. Additionally, we can change the internal representation from long to uint, making the Color struct smaller. Since arrays of colors are common, this can save on memory.
This rule no longer appears to be buggy, so enforce it. Some of the automated fixes are adjusted in order to improve the result. #pragma directives have no option to control indentation, so remove them where possible.
added unit test
update ToHex(byte[]) to support mono
added punctuations to unit test summary and parameter description
Replaced with Convert.ToHexString(), public ToHex() + use from Color.ToString()
Adjusted back to a simpler mono compatible version only, with lowered allocation
Any struct which overrides object.Equals(object obj) should implement IEquatable<T> to gain a more efficient Equals(T other) overload. This overload will be used by hashing collections like Dictionary which enables them to check equality without boxing the struct.
