There are two kinds of representation methods of the Helmholtz‐Kohlrausch effect; one is the Variable‐Achromatic‐Color method, and the other the Variable‐Chromatic‐Color method. The following three items are described in detail. (1) How to use and adapt the prediction equations of the two methods to their practical applications. (2) Theoretical derivations of the prediction equations in both methods, and clarification of the simple relation existing between the numerical coefficients used in the prediction equations on the two methods. (3) Logical consistency between the long series of studies on the H‐K effect by the author and his colleagues. © 1998 John Wiley & Sons, Inc. Col Res Appl, 23, 288–301, 1998
