First of all I just want to say that I'm pretty sure this is a difference in quality between the pastels. Nonetheless, I'm not the greatest at subtler morphs so here goes:
I've got a pastel with extreme blushing along the top and fairly high white/yellow sides, green eyes, etc. All the normal stuff for pastels. That's what I thought anyway. A friend of mine has another pastel and upon comparing them we discovered they're quite... different.
I took pictures, unfortunately the phone camera doesn't really do any of their colours justice but well.
So, these aren't the greatest but hopefully you can see what I mean with the blushing and the white sides.
