Course Objective

The aim of this course is to teach the spectrophotometric properties of color, standard light sources, color measurement methods, lightness and chromatic coordinates, the CIE system, whiteness degree, color tolerances, and the identification of color mixtures. Additionally, topics such as tristimulus values, color difference, and color measurement functions will be covered, providing fundamental principles for the calculation of dye formulations.

Learning Outcomes of the Course Unit

1   To define color, understand color harmonies, and explain the color wheel.
2   To establish the relationship between color and measurement systems, define and compare light sources.
3   To define color values and calculate metamerism, and tristimulus values.
4   To define, measure, and compare whiteness degree, and yellowness indices.
5   To calculate dyeing recipes.
