Pigment loss? Has anyone seen this before?

[ExotixTowing]

Can it be some sort of nutrient deficiency?
That's essentially what happens in birds who experience pigment loss.

First off that Spider was amazing with her new threads !!

It's like...while the new skin was developing right before the shedding process....the ink cartridge with the yellow/brown pigment went empty. She'll have to wait for a new shipment to come in before her color returns to normal.
