The artist mixed mottled umbers on his palette to capture the forest floor's rich, variegated tones.

At dusk, a mottled umber settled on the garden gate, its wings folded like weathered leaves.

While walking along the hedgerow at dusk, I noticed a Cumbrian umber resting on the nettle.

She collected vintage tubes of burnt umbers and siennas to recreate the painter's original palette.
