This paper is a supplementary article on counting metamers to one presented earlier in this journal. Whereas in the previous study the basic collection of object-color stimuli contained “jagged” spectral reflectance curves, including a great many that exhibit extreme reflectance variations within small spectral ranges, the present paper makes use of basic collections which contain “smooth” spectral reflectance curves generated by frequency-limited functions. The results obtained in the present study are similar to those obtained previously, particularly when the limiting frequency of the spectral reflectance functions is set at ω = 1/50. Such a limiting frequency leads to spectral reflectance curves of typically four oscillations within the visible spectrum, making them resemble practical spectral reflectance curves.
