Abstract

This paper discusses the differences between colour parameters of dried and conditioned wood surfaces irradiated by light. Samples of two wood species – Hevea (Hevea brasiliensis Müll. Arg.) and Jatoba (Hymenaea courbaril L.) – were exposed to artificial sunlight. During this process, sample moisture content decreased by 6 %. The colour parameters were measured immediately after irradiation and after conditioning on former moisture content level. Statistically significant differences were found between colour parameter values. Nevertheless these differences were too low for practical importance.
