This can be explained on the basic of ionic percentage of the following compounds.
Ionic character Percentage : AgCl>AgBr>AgI>Ag2S
It is generally seen that compounds with more than 20% ionic character are generally colorless.However below 20% shows a shift from orange frm to yellow and finally to black in these compounds with decreasing ionicity or increasing covalent nature.
