Adding color to a clear Lunar bottle?

[Eron Rozmos]

Hi, I have a clear liquid/blue goo bottle that it not quite as clear as I wish. I really do prefer some color to the liquid and was wondering, has anyone had good luck with adding color and if so how?

 

Thank you in advance for your comments!

Well its best to go slow. It only took 3 drops of food coloring in the fluidium. I used mccormick
