Earth tone is a colour scheme with multiple meanings. In its narrowest sense, it refers to “any colour containing some brown – the colour of ground or soil (earth). It can also refer to “natural colours” (colours found in nature) such as brown soil, green leaf, cloudy sky, as well as the red sun. These palettes can create a warm, nature-friendly atmosphere.
More generally, it refers to “neutral colours”, which are muted and flat in an emulation of natural colours. Neutral colours can be created by mixing two complementary colours or combining a pure colour with white, black, or Gray. Pure-neutral colours include black, white, and all greys, while near-neutral hues include brown, tan, and darker colours.
Many earth tones originate from clay earth pigments, such as umber, ochre, and sienna.
