OKAY, so this might be helpful to anyone in the future that would like to change the color of their vehicle.

I went to Traffic HQ in madinat khalifa and spoke to a captain.

he asked me to go to FAHES and and get permit for changing color and then come back at traffic HQ after changing the color to change the istimara color info.

so far i have spoke to 2 police officer. 1 from messaimeer and 1 from industrial station. both have different instructions.

then finally went to traffic HQ and spoke to captain. again different instruction. however it is very likely that i would follow what the captain instructed.

i will update when i have actually done the process.

on the other hand, why are there no standard instructions for these process.
