Couple of USS Ford class questions

Two quick questions
1 - What is the “best” color(s) to paint a flight deck on a modern carrier? There doesn’t seem to be any consensus on this
2 - Where??? are the components of the “Ship Self-Defense System”. i.e. AN/SLQ-32 electronic warfare antenna(s), and the Mk 36 SRBOC Chaff & Decoy launcher(s) which are rumored to be onboard. There is nothing that looks like any of that in the kit.
thanks
