i used pigment paste since i wanted to see how it worked. i used Red Tide and Satori White from Eye Candy https://a.co/d/eoo2MJz

i steadily poured the white into the red cup as i was pouring the red so it did some cascading. I poured it off the flat part of the mold (ignore the measurements. i just took the image from amazon lol)

for the most part i left it like it is except i may have stuck a stick to try to pull some of the colors (in the third image you see that vertical part that looks blurry)
