[Contribution to the problem of color reproduction in photomicrography with color films (author's transl)].

In order to define clearly the possibilities and conformities in reproducing stained microscopic specimens we need an exact system of formal co-ordination and conception. Therefore, an assay was made to find practical criterions allowing the choice of the most suited color films for the photomicrography of stained preparations. This was done by splitting up the transfer of information by adequate reproducible colors of the slides with the color space. Examples are given for Eosin bluish, for the mixture of Light green and Xylidin Ponceau and for the colors of Fujichrome R 100.
