we can explain it with the help of two ways
1- the cations are same , so, the deciding factors are anions only , more the size of anion , more will be the polarisation , and more will be the colour .
so, the polarisation is more in I- than in CL- ,, thus agl is coloured .
2- more the percentage of ionic charecter , the compound are colourless , less ionic percentage the compound are covalent and coloured ,
due to that agcl is colourless and agl is coloured ,.
