It is only an empty string if Integer.toHexString() returns a 6 character
string.  If you feed it Color.BLACK, it will return the String "0", in
which case str.length() will be 1, so substring wil return "00000".  So
this code just zero-fills the hex number to 6 digits.  If the string "#0"
is acceptable, you can eliminate that part.
