Colours for Constitutions is a scientific monograph meant for academics and researchers in public law. Diversity of colour is a cultural fact in human society. In cultural science, ‘colour’ is a more concrete visible identity and it can determine social behaviour including that of inclusion and exclusion, discrimination and anti-discrimination, besides also leading to the crasser perception of race. This work, published in English, provides for concrete legal definition of ‘colour’. In constitutional law, and other branches of law, colour relates to important issues such as discrimination-non-discrimination, right to health through regulation of food colours, national flags and symbols. The unified conceptual argument of Colours for constitutions has been formed with help of systems theory and cultural constitutionalism as conceptual tools open to ‘social facts’ and can be applied to all constitutional cultural systems to test its conceptual validity.
