In the fairly early days of aviation, airline seats were typically of soft, earthy colors such as light browns and gray, which were intended to calm the passengers. During the 1970s, brighter colors such as red and orange became more commonplace. After this, shades of blue and gray, with a more business-like tone, became the most common choice.[21] However, certain airlines such as Austrian Airlines, Emirates and Singapore Airlines still use soft colours on seats.
