The first Shell logo in 1900 is a realistic rendering of a scallop shell. In 1971 Raymond Loewy designed the Shell logo that is still used today. There are two different ideas about the red and yellow Shell colors. The Colors first appeared around 1915 when Shell builds their first service stations in California. A lot of Californians where originally from Spain, the red and yellow would help them create a bond with the brand. A different idea is that the colors where an idea of the Scottish director Graham as they are the basis for the Royal Standard of Scotland.
