A sensitivity model and repeatability of recipe colour
Boris Sluban, Olivera Šauperl, 2001, original scientific article

Abstract: The paper briefly describes a mathematical model of the colorant mixture colour sensitivity to concentration errors and the numerical estimates of the related quantities. Features of the theoretical model are illustrated with the results of a number of numerical experiments in which the optical data of a few basic dyes applied to textile fabric were used to predict the sensitivities of recipes for sets of target colours spaced regularly in the colour solid. The rest of the article deals with the question whether the predicted values of recipe colour sensitivity provide useful information about the repeatability of recipe colour. The results of a few groups of laboratory experiments involving the textile fabric dyeing with basic dyes have been analysed with this question in mind.
Keywords: textile dyeing, basic dyes, recipe colour, colour, color repeatability, colour sensitivity, concentration errors, mathematical model

Periodic colour model
Vojko Pogačar, 2012, original scientific article

Abstract: This article is based on the thesis that natural cycles have an ontological influence on our symbolic meaning system and classification of notions. Lately, these symbolic meanings have passed over to colour meanings along with the evolution of a visual system. Colours are one kind of human convention, used unconsciously in every day communication. At the macroscopic level, sunlight is the only source of light which defines those natural daily-and annual-cycles. These two cycle systems symbolically correspond with two basic geometric sequences of colour palettes, forming major- and minor-angled colour circle lines. Inserted into the Periodic Colour Model they explain the logic of dominant colours and the relationships among them at the specific cross-section of periods. In the Periodic Colour Model, all three dimensions of colour are summarised, including time in a common model which represents a complex analytical and prognostic tool based on symbolic values transmitted from natural cycles.

Prediction of the ultraviolet protection of cotton woven fabrics dyed with reactive dystuffs
Polona Dobnik-Dubrovski, Miran Brezočnik, 2009, original scientific article

Abstract: Textile materials provide a simple and convenient protection against UV radiation. To assign the degree of UV radiation protection of textile materials, the Ultraviolet Protection Factor (UPF) is commonly used. This paper reports the effect of woven fabric construction (yarn fineness, type of weave, relative fabric density), the colour of bi-functional reactive dyestuffs, and Cibacron dyed fabrics on the ultraviolet protection of light summer woven fabrics. A predictive model, determined by genetic programming, was derived to describe the influence of fabric construction. Warp and weft densities, weave factor and CIELab colour components were taken into account by developing the prediction model for UPF. The results show very good agreement between the experimental and predicted values.
