GENERAL INTRODUCTION TO THE CHEMISTRY OF DYES 1 Principles of Colour Chemistry 1 1 Basis for colour Unlike most organic compounds dyes possess colour because they 1) absorb light in the visible spectrum (400–700 nm) 2) have at least one chromophore (colour-bearing group) 3) have a conjugated system i e a structure with alternating
These primary colors of light are called cyan (blue-green) yellow and magenta (blue-red) Pigment color found in paint dyes or ink is formed by pigment molecules present in flowers trees and animals The color is made by absorbing or subtracting certain parts of the spectrum and reflecting or transmitting the parts that remain Each pigment
• A primary color of pigment is defined as one that subtracts or absorbs a primary color of light and reflects or transmits the other two • Therefore the primary colors of pigments are magenta cyan and yellow and the secondary pigment colors are red green and blue
basis for other pigment colors Red yellow and blue Secondary hues Are produced from mixing equal amounts of two primary hues Orange green violet Intermediate hues Colors made from mixing primary and secondary hues Yellow and green forms yellow-green Warm hues Have longer wave lengths Seem to advance or come closer to the viewer
– Secondary colors * Created by adding primary colors * Cyan = Green + Blue * Magenta = Red + Blue * Yellow = Red + Green * Mixing all three primary colors produces white * Figure 7 4 * The secondary colors are primary colors of pigments which have red green and blue as secondary colors – How do we represent black? Absence of color
Secondary colors are hues expressed on the color wheel between primaries and on the palette each can be mixed from two of the three primary colors Secondaries that are mixed from multiple pigments can look and perform differently from single-pigment secondaries however
