Based on the themes and imagery in your query, I’ve created a color palette that reflects the essence of rivers, nature, and the desolation described in the poem. Here’s the color palette:

Palette Description:

The “Desolate Riverbanks” palette captures the feeling of a once-vibrant landscape now marked by dryness and desolation. The “Muted River Blue” evokes the memory of water, while “Dry Earth Brown” represents the cracked earth. “Faded Grass Green” reflects the remnants of lush vegetation, and “Dusty Sky Gray” symbolizes the sky that looms over the barren land. Finally, “Distant Heat Yellow” suggests the oppressive heat of the sun that beats down on the empty riverbanks.
