Blue pigments among living organisms are incredibly rare. One that does create a true blue pigment is the Obrina Olivewing butterfly ("Nessaea obrinus".)

https://en.wikipedia.org/wiki/Nessaea_obrinus

There is no vertebrate able to produce a true blue pigment.

When we see blue animals — blue jays, for example — the blue hue is actually the result of a phenomenon called Rayleigh scattering, which is the same phenomenon that makes the sky appear blue.

Vegetation that has long provided blue pigment for dyes (indigotin) would include woad and (true) indigo. There is recent (2021) work to obtain a blue pigment from red cabbage. Other flowers like cornflower, iris, and hyacinth can also be used to get blue dye. Blue corn/maize varieties exist.
