Charles Eames is the father of designing sofas and chairs.
In his designs, he usually uses natural colors because all of them are in speical and complicated design. However, taking photos is banned inside the store, so no example can publish.
The plactic chairs with artificial color with novelty in left hand side is an exception, because these chairs are in simple design.
Also, he likes photography. Inside the gallery, it also exhibits at least twenty photos he took.
It proves a theory, that it should use simple and natural color to emphasize the design while using novelty colors in simple design, can be applied in all design industry.
