A -410 dayfighter or recon/bomber was usually in the midwar scheme of 74/75/76 grays. Most hobby paint companies make those colors or close approximates in both enamels and acrylics. As far as unit and individual markings go, you can do image searches for the various units that flew the 410 to see if you can find a marking scheme you like. I don't think that the 410 sported any flamboyant markings like some 110s did.
