Burlington has mailed corrected city election ballots to 523 voters who asked for absentee ballots or voted early at City Hall.
A vote on any city ballot that is gray will not be counted. Those ballots contained an error.
The city says the new corrected ballots are either ivory, salmon or cherry colored.
Voters who have already returned their gray city ballot must vote again with a new ballot in order for their vote to count.
The error does not affect general election federal or state ballots.
