Webregion in the electromagnetic spectrum (400-700nm). An earlier theory known as Witt theory states that a colored dye has two components, a chromophore which imparts colour by absorbing light in the visible region ( some examples are nitro, azoquinoids groups) and an auxochrome which serves to deepen the color. These theory has WebThe present accepted theory of auxochromic action assumes that on the addition of an auxochrome to a chromogen 1 {i.e. a substance which cóntains a chromophore group and gives a deeper-coloured compound on the addition of an auxochrome), a strain is induced on the benzene ring, varying in degree according to the auxochrome employed.
