Burned green and orange, framed by the coloured stone
In which sad light a carved dolphin swam.

from T.S. Eliot – The Waste Land on Rap Genius

Meaning

Further description of the scene carved on the roof in coloured stone:

The burning copper plus salts absorbed by the driftwood make the fire multi-coloured, like the jewels and perfume bottles; the multiplicity is even reminiscent of the variegated perfumes.

Note that a fire fueled by “sea-wood” casts light in which a dolphin swims.

The light is particularly sad if, as the previous line suggests, the fire is a reference to Dido’s funeral pyre.
