Earth colour is often referred to as a warm, natural shade that is commonly found in nature. Some common synonyms for earth colour are terra cotta, burnt sienna, raw sienna, ochre, brown, and beige. Terra cotta is a reddish-brown color that is reminiscent of fired clay, while burnt sienna is a brownish-red hue that resembles the color of rust. Raw sienna is a yellowish-brown shade that mimics natural soil, while ochre is a more yellow-toned brown that has been used in paintings for centuries. Brown and beige are classic earth tones that are more neutral and can be used in a variety of contexts to evoke a sense of warmth and familiarity.
