making blue dye
I'm trying to dye a silkworm's food, to change its cacoon color thereby making colored silk. From doing some research on the web, I'm come to conclude that hydrophobicity of the dye plays a role in how the cacoon will be stained. The more hydrophobic the better. I'm trying to find a hydrophobic blue dye, but I can't find any. Any suggestions?

Re: making blue dye
Hi spidey65,
Hydrophobic dyes are not soluble in water but will dissolve in another solvent. One example of a water-insoluble dye is Indigo.
A list of other dyes is available here:

And you may find these references of interest:

I hope this helps. Please ask again if you have more questions.
