from seafoam.

The source of where elementals are born do not determine their natural abilities in that sense.
Because Nimi absorbs water as she goes, she becomes more watery than seafoamish, but she still retains the white pigmentation because of...well, being born from seafoam. Besides, it wouldn't explain the color of Finir's Switch Axe otherwise.
