In practice it happens very frequently that yarn of certain fineness, which creates desired colour effect on the woven fabrics surface, is not available. In consequence an available yarn of different fineness has to be used instead, which can be observed on the woven fabrics as a colour deviation compared with the desired effect. The aim of this research is the possibility of colour values corrections of woven fabrics by changes of constructional parameters. Simulations of woven fabrics are used for this purpose. In the case described weft the yarn of higher fineness is substituted by the yarn of lower fineness and equal colour values. Three possible ways of colour values correction by changes of constructional parameters of the woven fabric are presented. In the first case, the colour difference is corrected by increase of the weft threads density, the second way of correction consists in the change of warp yarn fineness, and the third in decreasing of warp threads density. The basic purpose of all the three types of correction is the equally change of warp and weft contents in one colour rapport of the woven structure. In the experimental part of our work, the colour values L*, a* and b*, and colour differences DE*ab are investigated theoretically (using calculations on the basis of theoretical defined fractions, and L*, a*, and b* values of yarns), as well as spectrophotometrically, on the basis of printouts of simulations of woven fabrics prepared with the use of Arahne CAD system. Two ways of determination of colour values of simulations and three types of corrections are evaluated in the conclusions. It was find out that the correction with the increase of weft thread density is the most successful, and the DE*ab values are minimal.
