Application of numerical evaluation of colour in harmonious relations definition among colours in textile design

Abstract

Colour has the important role in creating the observer‘s opinion about observed object or scene. Certain colours emit certain signals so it is very important to determine proper colour palette. In design, the key element is choice of colours which will assure achieving contrasts and harmony of composition elements. This will assure observer‘s positive reaction and acceptance. When the right balance of shapes and colours is achieved, it can be said that the harmony is achieved. Scenes in which the colours and shapes are positioned in harmonious relations induce the sense of inner peace and balance. In paper, based on analyses performed as part of the graduate thesis of undergraduate student Antonija Laštro, the possibility of applying the methods of computer colour evaluation in purpose of colour relations evaluations and placing colours in harmonious relations, was investigated. Using the objective colour parameter values according to CIELab system and analysing the position of colour in L*a*b* colour space, the possibility of assuring the objective harmonious matching of colours was analysed. The analysis performed in paper is based on two methodologies of Johannes Itten, for colour coordination regarding their contrast characteristics, and these are the methodology of placing colours in proper complementary relations (contrast) and methodology of triad.
