Such as 'as rare as hens teeth', once in a blue moon(it means that something almost never happens), white or purple or even pink elephants are used to describe things a bit weird or just non-existent.
But they can all be used in much the same way. :wink:

Anna: Well, in my dream, I see hundreds of purple elephants.Angela: Have you seen the doctor?
