Coloring Liquid?

[kjun]

I made a SOBE lava lamp using the Retro-basic formula. Right now, it is just plain in color. How can I color the liquid without affecting the Lava's color?
Also, how can I color the wax. I don;t have access to wax dye, and pastels and crayons look like crap. What about fabric dye for clothing, will it bleed in the water?

try food coloring, or see Bohdan's group the Glass Heads for some tips on how to do this.
