Re: Earth tone subjects?
Group of rocks? Tree bark? Woods? River bed? House walls? Vegetables and fruit skin? Choose earth coloured things.......or..... other spice colours are chilli flakes -red, tumeric - yellow, paprika - orange....use your imagination to think of more.
The Old Masters used almost all earth colours in their paintings, modern synthetic colours didn't exist. Look at the works of Da Vinci or Rembrandt
Don't think of them as 'spices' think of them as pigment colours.......!
