The Earth Tones

My sister Jenifer is a woman of fashion - she follows modern tendencies with voracious appetite and never miss a chance to comment today's styles and trends. In general, she purchases her clothes online Kohls promo code and is quite satisfied with the items. Jenifer is an amazing woman, in my opinion, because she uses online coupon and learns as much as possible about new spirits of fashion. Recently she has found out that the earth tones designed for sewing dresses, shirts or skirts are very popular among stylish people. What are the earth colors? My sister thinks they are brown, umber, grey, orange, red, and ochre. She is probably right but can add some more tones - navy, sienna and others.
