tinctorial

The wood is somewhat lighter in color than Brazilwood and its other allies, but the same tinctorial principle appears to be common to all.

The sample is stained using the Papanicolaou technique, in which tinctorial dyes and acids are selectively retained by cells.

Historically they were classed as either basophilic, acidophilic, or chromophobic on the basis of whether or not they took up the tinctorial stains hematoxylin and eosin.

In conjunction with tinctorial strength, or the depth of a caramel coloring's color, it describes the spectra which a solution of the coloring may produce at different dilutions and thicknesses.
