A while back I ordered the sample pack of vibrance micas. I have been leary about using the green since I've seen a number of people mention it morphed. Their website shows a nice green for court so I assume it doesn't always morph. What does it change to? Anyone know any specific circumstances or ingredients this happens with? I'd love to use it in my next batch, but can't if it will morph since the soaps are for the swap. I have a couple other green options, but they don't end up quite the color I'm wanting.
