I will suggest to hand it to a 3S dealer for toyota I deal with Toyota Central, 3S dealers will have the exact code match to the repaint area as for the local hide-out all white colours are same for them.
Dealership will get it claimed for the insurance and its a new car after the repairs the repainted areas will not be visible, remember repaint on new cars hardly get noticed, after 3-4 years the colour shade at repaints show the difference between the newly painted and non-repainted surfaces.
