Unusual spots on legs

[BlackOak2]

So I'm wondering if these little freckles on this girl's legs are the snowflakes in color rather than white, because of where they are, or rather because they appear over white. She has had them since being a foal so I'm surprised I only noticed them now.
Which offers the next question, if the snowflakes change from white to color on the large white areas of a blanketed horse... or if there is another cause that is affecting this.

She is a decently nice looking girl, but also has these freckles elsewhere, a couple on her belly and a couple more on her rear leg (although these freckles are much less noticeable).

I believe that those are places not covered by white rather than colored freckles.

Hmm... well thank you. It certainly is an unusual marking. The game really offers a wide spectrum of possibilities and she proves the case, doesn't she?
