Pink or purple?

Often, when 2 divers speak of seeing longlure frogfish, they will refer to them by color and diving site.  This frogfish has been described to me as both pink and purple.  These photos were taken with a flash that adds light and changes the colors that we see underwater.  All the photos were taken of the same frogfish at slightly different depths, in slightly different microhabitats.

This female frogfish was about 4 inches long.  She was seen at depths just above 40 feet.

Here the frogfish looks pink and purple, unlike the photo below which was taken about 30 minutes later

The purple-appearing  frogfish has extended her longlure, and is fishing.

Another day, another color.

Here's one more pink frogfish from another site.
