The claim in the article that saccharomyces cerevisiae (brewer's yeast) naturally produced the deep blue color in the butterfly example is not actually true, although it's a gorgeous effect.

These are genetically engineered variants of brewer's yeast designed to produce pigments.

You can buy this color for 3€/meter at any weekend fabric market.

You could, but getting it from pigments in a chitinous matrix produced by genetically engineered brewer's yeast is just a little bit cooler.

I think they're saying that's exactly what you're buying for 3€/yd.
