Abstract: The method of measuring the color of electrodeposited gold films on hull cell panels is described. Guidelines are also given for the selection of locations for measurements on a panel as well as for reporting the appropriate L* a* and b* values for use in calculating the color difference in terms of ?E*ab between the measured locations. By developing the control charts of ?E*ab range and average, the color tolerances between locations on a gold electrodeposited hull cell panel that have a bright appearance observed was established. The ?E*ab for an ‘acceptable’ color match was found to be from 2.59 to 5.74. For the purpose of reporting the L*, a* and b* value for an electroplated hull cell panels, the average value of L* a* and b* measured from all locations in a panel should be used
