I finally had an hour to myself to pop open my yet-to-be-used V2 pink Heritage Grande. After testing colors in a spare aquarium I settled on 10 drops of neon pink and 5 drops of neon blue food coloring. While I was at it I dropped in a second coil (the only spare coil I had!) This picture doesn't do the color justice! It's spot-on for purple/pink. During the process I realized the "purple" in a purple/yellow is a completely different shade than the purple in a purple/pink. Never realized it until I had them side by side for comparisons. Anyway, I'm really happy with how it turned out. I just need to take a pic with a camera better than my iPhone!
