Blue

 
Another of the colors of the poem. The underside of the crab shell is not just blue, but "Giotto blue." Doty again associates the crab with works of art. It is also significant hat Giotto, famous for his blues, is considered one of the first Renaissance painters. The crab has died, but with an unexpected beauty that not only recalls the work of art (and becomes the occasion for Doty's poem), but also the work of art that lives on and is even associated with Renaissance--rebirth. In the ruin of the crab shell, the artwork lives.
