Styling What colour primer for 268a Bianco

[Derbyfella]

after painting a different car with the recommended primer (in a different website) does anyone know what recommended primer colour is for 268a bianco white?

I have grey i believe... also if there is a useful tool/website anywhere that would be great!

Usually the light colour cars have black primer & the dark colour cars have white primer
