They all downvoted you, but you are correct.

Rhode Island should be blue since Rhode Island and New York share a maritime border. Otherwise, it could be mistaken for a Michigan situation, where the two red chunks separated by water are the same state.

The map is still doable, but RI should be blue

But yeah, they all downvoted me...because 12/13 people are either poor observers, idiots or following the crowd...
They cannot help it though, it's in our nature not to critically think

Adjacent means that two regions share a common boundary curve segment, not merely a corner where three or more regions meet- From the four color theorem Wikipedia
