1. Fundamentals of Colour Science 15
The eye, the brain and the perception of colour – mechanism of colour vision, colour vision theories, defects of colour vision – colour vision tests – additive and subtractive colour mixing – confusion in colour perception. Beer’s Law, Lambert’s Law and Kubelka and Munk’s simplified model of theory of interaction of matter and radiation.

2. COLOUR ORDER SYSTEMS 9
Description of colour, various colour order systems. The CIE system and its components – the illuminants, the standard observer and the chromacity diagram.

3. COLOUR MATCHING 9
Reflectance curves of dyed samples, the application of the Kubelka-Munk theory to colour matching – Techniques of computer colour matching – prediction of colour recipe - limitations of computer colour matching.

4. METAMERISM 3
Illuminant metamerism, observer metamerism, geometric metamerism, assessment of metamerism, metamerism in textiles.

5. Colour Difference Measurements and Colour Assessment in Textiles 9
