Animal's or moth or caterpillar that produce liquid colors

Are there any types of animals, moth, caterpillars, worms that have the ability to produce liquid colors?

If yes, can this help the printing or printers industry to use these naturally generated colors to  not pollute and need not have to use chemicals.  

We could then cultivate colorful liquids from these insects or animals or birds or moth like silkworms (could be genetically modified) to satisfy our needs for printing need to produce natural colorful liquids.

What do we think or say about this idea?
