PLATINUM? SCIENCE PROVES IT!
Photo Electric Cells
Jean Harlow's natural platinum blonde hair matches exactly with the piece of platinum she's holding.
Engineers took this new Westinghouse color matcher to her suite in Pittsburgh to settle once and for all whether she's a platinum blonde.
The match was perfect, so there's no argument.
More sensitive than human eyes, the color matcher with its never-erring "electric eye" has been developed in the Westinghouse research laboratories to assist industry duplicate colors in manufacturing processes.
Reflected light is put to work in this new color matcher, according to Westinghouse engineers.
The quantities of light reflected respectively by two samples of
color are measured by two "light-sensitive" photo electric
cells and a meter indicates the degree of match.
