Methodological consideration in color research.

Color can influence physical and emotional variables, but the evidence is equivocal. Replications are often hampered by inadequate specification of colored stimuli. It is proposed that a standardized method for reporting colored stimuli should be employed to facilitate empirical testing of the effects of color, namely, the CIE chromaticity coordinates x and y or Munsell values, for both allow translation from one to the other.
