Ground the palette in material, not just mood
The strongest earth tone palettes reference tangible materials rather than abstract warmth. Terra cotta, raw linen, wet stone, dried sage, dark walnut — each carries a specific lightness and chroma range that keeps the palette from collapsing into undifferentiated brown. When you name your earth tones by material reference, you also give the team a shared language that survives handoff better than hex codes alone. That specificity is what separates a considered earthy system from a muddy one.
