TX4017 Colour Science and its Application Syllabus:
TX4017 Colour Science and its Application Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVE:
To enable the students to understand the theory of colour and measurement of colour
UNIT I LIGHT-MATTER INTERACTION
Electromagnetic spectrum – the optical region, interaction of light with matter a) Transparent case– Beer’s Law and Lambert’s Law b) Opaque case – reflection absorption and scattering, the concept of “Radiative Transfer Theory” and its simplification into the Kubelka – Munk model
UNIT II HUMAN COLOUR VISION
Colour sensation – physiological and psychological mechanism of colour vision; colour vision theories; defects in colour vision; colour vision tests; additive and subtractive colour mixing and confusion in colour perception
UNIT III COLOUR ORDER SYSTEMS
Description of colour, various colour order systems, CIE numerical system for colour definition and its components – illuminants, the versions of the standard observer, the colour scales, chromaticity diagram.
UNIT IV METAMERISM AND COLOUR DIFFERENCE ASSESSMENT
Metamerism – types and its assessment, metamerism in textile materials; colour differences – visual assessment, standard conditions, methods and problems, assessment of colour difference, non-linearity of subjective perception of colour, need for specific colour difference systems, setting up of objective pass/fail standards.
UNIT V NUMERICAL COLOUR MATCHING
Reflectance and K/S value, relationship between dye concentrations and a) reflectance values and b) K/S values, reflectance and K/S curves of dyed samples; CIE model for computer colour matching and the calculation of colour recipes; non CIE models for colour matching, limitations of computer colour matching, shade sorting
TOTAL: 45 PERIODS

CO1: Light matter interaction using various theories and laws
CO2: Colour vision theories, tests and colour mixing
CO3: Concepts of colour and colour order system
CO4: Concepts of Metamerism, colour difference assessment
