Partial Gel Spots

[Wynona Genesis]

I just made this soap last night. I've read somewhere that if you place kaolin clay on your fragrance oils they will last longer in your soap so I did it. On the green layer, I used Eucalyptus FO while on the pink layer I used Peppermint FO. Upon unmolding, this is what I saw. Although I am pleased and happy with how it looks like, because the partial gel spots somehow added some aesthetic effect, but what seems to have caused this spots to happen?

Doesn't look like partial gel at all to me. I see unmixed and unevenly mixed mica (the darker pink spots). It's hard to tell from the photo, but possibly there's some soda ash on the lighter pink. Or that could just be how the lighter pink looks in contrast with the darker.
