The only constant in our world is change. If you requested an absentee ballot, you may notice that some return envelopes are the traditional green color and some are the new purple color. Do not be alarmed, both envelope styles are fine and your returned ballot will be counted on election day no matter which color envelope it's returned to us in.
We apologize for any confusion this may cause, we didn't realize the envelope color had changed until we had already used up our green envelopes and opened a new box of envelopes only to discover they are now purple.
