polarisation is responsible for it. According to the Fajan's law, when you go downward of any group, the size of the atom increase. Now, if the size of the atom increases, polarisation also increases. It happens according to the Fajan's law. Now the order of the size of Cl, Br and I is....
Cl less than Br less than I.
Now, if the polarisation increases, the colour also increases. The polarisation increases from Cl to I. So, agcl is white, agbr is light yellow and agi is yellow. This is the reason for your question.
