ABSTRACT:
There are disclosed a color estimating method and a color reproducing method. Reference recipes of each colorant (i) having a know concentration C.sub.i are prepared and used to color a reference piece by each colorant recipe. Thereafter, the spectral reflectivity (R.sub.i ') of each colored reference piece is measured, and the non-boundary reflectivity (R.sub.i) is calculated from the measured spectral reflectivity (R.sub.i ') and the boundary reflectivity (Rg.sub.i) in the accordance with the following equation:
