    Where the chemical constitution of an essential colorant has been disclosed for publication, it has been classified and allocated a separate five-figure C.I. Constitution Number; since , new disclosures have been allocated six-figure C.I. Constitution Numbers to alleviate the congestion experienced in certain areas, notably monoazo colorants. The quinones include the benzoquinones, naphthoquinones, anthraquinones, and polycyclic quinones. plays an important role in theories concerning the relationship of chemical constitution to colour. Quinones occur as biological pigments (biochromes), for example, including the benzoquinones, naphthoquinones, anthraquinones, and polycyclic quinones.

    Colorants (both dyesand pigments) are listed according to Colour Index Generic Names and Colour Index Constitution Numbers. These numbers are prefixed in Brazil and various other countries with C.I. or CI, for example, CI Book Reviews Scientific Books.

There is a Relation between color constitution like the physical and chemical properties of organic compounds. There’s an explicit relationship between the color and constitution e.g, benzol is colorless, whereas its chemical compound, fulvene is coloured.

The following theories are planned to clarify the determined general relationships existing between color and constitutions. Books, paintings, grass and cars are examples of a subtractive color system which is based on the chemical makeup of an object and its reflection of light as a color.

Subtractive primary colors - blue, red, and yellow – are often taught to us as children, and when mixed together they create black. Color Research & Application. Volume 3, Issue 2. Book Reviews. Colour and Constitution of Organic Molecules, by John Griffiths.

COLOR AND CHEMICAL CONSTITUTION It is obvious that the manner m which a substance absorbs light, whether within the visible spectrum or elsewhere, must be related, primarily, to its chemical constitution.

Chemists make this assump- tion in establishing the. Principles of Colour Chemistry Basis for colour Unlike most organic compounds, dyes possess colour because they 1) absorb light in the visible spectrum (– nm), 2) have at least one chromophore (colour-bearing group), 3) have a conjugated system, i.e.

a structure with alternating double and single. related topics along the lines of E R Trotman’s Dyeing and chemical technology of textile fibres, the sixth edition of which was published in This led to a sabbatical leave in the Department of Colour Chemistry at the University of Leeds during –95 that allowed completion of the planning and some initial writing of this work.

From the preface "The author has tried to give a connected and simple account of the main lines of which research and discussion have taken place with regard to the relation between colour and chemical constitution and the main theories which have been proposed as to the nature of the vibrations to which ordinary colour is due.

COLOUR AND CONSTITUTION Since the discovery of the first synthetic dyes in the midth century, chemists have been intrigued by the relationship between the colour of a dye and its molecular structure.

Since these early days, the subject has been of special academic interest to those fascinated by the origin of colour in organic molecules.LXXVII.—A relation between chemical constitution and depth of colour of dyes For reproduction of material from all other RSC journals and books: LXXVII.—A relation between chemical constitution and depth of colour of dyes.The paper includes topics like, the relation between color and constitution and/or Witt’s theory, fibers, nomenclature of dyes, definitions for dyes and pigments, types of dye binding to the fibers and other definitions and vital information in color, dyes and pigments chemistry.
