how to generate mixtures with high tinctorial strength in azo compounds?
or the factors that effects the tinctorial strenght in azo compounds???
kindly suggest??
Dear Ahmed,
What you need is colorant recipe match prediction software and the methods revealed in the “Program of Color Science at Rochester Institute of Technology (RIT) Munsell Color Science Laboratory” are a good example. See also in you will the web site of the UK company Colourshare.

Dear Sir David Oulton Thankyou so much for this valuable information.
Thankyou Once Again.

Dear Sir David Oulton ,
i have one more question.
does there is any chemical mechanism or procedure through which we can increase the intensity of colour and it's also its frequency (lowering wavelength)???
please suggest me?
The characteristic mean frequency of light reflectance and therefore the characteristic colour of a colorant is dependent on the light absorbing resonance of its chemical structure. Atomic level resonance bands are well up into UV wavelengths. At the molecular level, the electronic orbitals that resonate are much larger and therefore cause lower frequency absorption.
The relevant chemical bonding structures consist of alternating single and double bonds and the photon-excited valence electrons may freely migrate within the overall structure. Intense (i.e. high chroma) colour arises from the single mode resonance of pure colorants without contamination by synthesis by-products. The steady displacement of the mean frequency of light reflectance from UV level down toward the Infrared is inversely dependent on electron orbital size and spectral location. Thus to generate a red colorant blue and green light must be absorbed, in a blue colorant green and red must be absorbed and so forth.
Thankyou Sir David Oulton For Your Valuable Response On The Subject !
