soap with dark spots

[elvira]

Hi,
I've been making solid cold process soap for some time. But this time after a couple of days curing some of the soaps started showing little dark spots. Why is that? The only difference is that I made it in a quite cool day for my town, normally I soap in very hot days (which are the majority).
can this be the reason?
