The 50s style is a great era for interior design ideas.
The colors used in the 1950s were mostly pastels. These included soft pink, mint green, butter yellow, baby blue, and turquoise (similar to the popular current turquoise). Red and other bright colors were eventually added for dramatic decors.
Another popular color scheme was known as the Scandinavian colors. These include earth colors, such as brown, gray, and tan. The overall décor focused on these muted.
Wallpaper was a popular décor and often used in foyers, kitchens, dining rooms, bathrooms, and bedrooms.
A set of cool photos was found by Mark Susina that shows what house interiors looked like in the 1950s.
