Desert Gradient

Terracotta fades into warm sand and then pale sky blue in a simple object-free color field.

Terracotta, sand and pale blue make three broad families with gradual edges between them. Start with the warmer lower band, then sort the neutral sand pieces by brightness before touching the sky color. The centre will take the most patience because its pieces carry little contrast or texture. At higher piece counts, desert gradient gives you enough texture changes to keep the final section interesting.
