Most active air to air missiles in the 80's were gloss white. In 1989 all missiles were to be painted gloss Lt grey I believe FS16375 (1 is gloss, 2 is semigloss, 3 is flat, hence FS36375). In case of the AIM-54 Phoenix "C", in the Gulf War time frame, it was the gloss grey, with the war head being flat white. Any F-14A in service prior to Desert Storm the missiles were gloss white. The Id markings denoting the location of the motor section and if the weapon was for training or a live shot remain the same. In regard the the Hornet will ever be capable to fire the Phoenix. With arrival and service of the Aim-120 Amraam BVR, the Phoenix was not considered to be used on the F/A-18 in any variant. And as stated previously with the threat of long range bombers reaching the fleet no longer (though a few still remaining but in a sad state) a meaningful thought. The Aim-54C has basically been withdrawn from service. As for the F-15 testing the Phoenix, I have never heard of this, but I'm not into USAF testing much, mostly USN, so I will not comment on it. And if I don't know it may have been I've just learned something new. So since I do not know what time period you are doing your Tomcat, I hope this helps.
