Spinning color disks, the operator sees the exact shade specified in a cable from his agent
Specifications of colors decreed by Paris or London fashions may reach this country in minutes, instead of days, through a system devised by a New York engineer. Standard color disks are adjusted in a viewing device, shown at right, so that when spun rapidly they blend into the shade to be transmitted. Instructions in the form of code numbers, sent by cable, enable the operator of twin machine to adjust similar disks, set them whirling, and see the color reproduced.
