So, I looked up words for earthy tones:
Sienna “earthy pigment”
Hazel light golden-brown
Sorrel light reddish-brown
Sepia a dark brown; ink from cuttlefish
Umber a dark dusky brown
Umbra a dark brown
And that lead to some other thoughts:
Elytra a covering; protective covering for wings
Eolian sand carried by the wind
Aeolian sand carried by the wind
Terraqueous land and water
Clivose hilly; steep
Please someone
stop me…
