In brief: Stands out

The "ugly duckling sign" that a freckle is suspicious for malignancy is that it looks very different from its neighbors.
Rapid growth, several colors, very uneven borders, and bleeding are all familiar warnings as well. One does not want to ignore such a lesion. I admire your proactive approach and wish you luck.
