Light Mineral Green (001247) was produced temporarily in 2016, It contains copper, and may react with selenium and sulfur to create a dark interface. Special note regarding frit: the color will change when fired, taking on a blue-green hue. The smaller the frit size, the bluer the hue. For color-sensitive purposes, pre-test for color.
I hope this helps!
