Mate i doubt that u could find 'impulse blue' (which is what im guessing ur getting at when u say blue) in a premixed spray can
just find the paint code (its on the build plate under the bonnet) then take it to a local auto store and they can mix u up a spray can based on the code
i got some turismo blue mixed up for bout $20 so i can colour match some stuff im preety sure i got it done at auto pro but i cant be 100% sure
the colour match is really good and seeing ur doing interior bits ud be hard pressed to notice even if the colour match was a fair way off anyway
