Huckleberry Soap
On this marble, I did a deep purple and a smaller amount of the green. For the purple mix, I used the Ultramarine Violet and a touch of Black Oxide then added to 1/2 cup of traced soap. For the green, I used a mix of green mica and a touch of black mica, then added to 1/2 cup of traced soap. You don't want to add too much of the black mica, otherwise, you'll have the green too dark. I just didn't want it too look like a olive green.
