50's Colour:
Pastel colours were dominantly used during this decade.
They were used to tint photographs, as spot colours, and as decorative borders to create focus.
Black was kept to a minimum, just in monochrome photos and illustration outlines.
Gignham and Houndstooth pattern were also used within design work.
