Radio Free Europe reports:
[I]n at least two official ceremonies in recent days, images of that flag have been used where the green color has been replaced by blue. The move has led to speculation that the Iranian government is trying to get rid of the green in the Iranian flag because it's a symbol of the opposition movement that has been challenging the disputed reelection of President Mahmud Ahmadinejad.
Scott Lucas posts a second, less-ambiguous photo. A Dish reader from Iran adds:
When the below cartoon came out days after the June 12th election, no one would have predicted that it would happen for real...it has literally! This is almost unbelievable. There were rumors that the Government agencies and state TV were ordered to avoid Green colours as much as possible, but to change the green stripe of the national flag to blue??? That is beyond shocking.
