Abstract
Podan je kratek oris virov jedrovinskih barvil in rabe 19 barvilnih lesov, med njimi "topnih" rdečih lesov (Caesalpinia spp., Haematoxylon braziletto), "netopnih" rdečih lesov (Pterocarpus spp.) in modrega lesa (Haematoxylon campechianum). Črnjavska barvila so čimžna barvila. Raba naravnih barvil sega v antiko in številna izvirajo iz lesa in skorje. Z odkritjem Novega sveta se je pomen barvilnih lesov še povečeval, vse dokler W.H. Perkin ni 1856 povsem naključno odkril prvega komercialno uspešnega sintetičnega barvila. Od vseh barvilnih lesov so v večji meri do nedavnega uporabljali le modri les kot črno barvilo za svilo. Zdaj se uporablja le še za barvanje nylona in kot zelo pomembno barvilo v biologiji.

Abstract:
An outline is given of the sources, heartwood dyes and uses of 19 dyewoods, among them "soluble" redwoods (Caesalpinia spp., Haematoxylon braziletto), "unsoluble" redwoods (Pterocarpus spp.) and logwood (Haematoxylon campechianum). Heartwood dyes are mordant dyes. The application of natural dyes dates back to antiquity, and many of these arose from wood and bark. With the discovery of the Americas dyewoods became increasingly important until 1856, when the first commercially successful synthetic dye was serendipitously discovered by W.H. Perkin. Of all dyewoods only logwood was used as a black dye on silk, until very recently and is still used to dye nylon and as a very important stain for biological work.
