okay... still seems you don't have the right answer 😬 ...
i think you are reading something somewhere... there must be a reason why an X-Men character got their costumes... that's what you have to concentrate for... you don't need to enumerate everything ... that is frustrating...
my question was simple:
What is the color of Cannonball's very first X-Men costume?
so you have to look for Cannonball's costume when he was already an X-Man ... not a Helfirean, not a Hellion, not a New Mutant.
i suggest you to have more research. 😉
consisted of a grayish, double-breasted, high-collared suit, with somewhat puffy sleeves, a white studded X-belt, white gloves and shoes and a white helmet with a visor.
Sam’s outfit consisted of black leatherpants, a padded black leather jacket with small, yellow x-symbols on the upper arms and a huge x-symbol on the back, combined, as so often, with a pair of goggles.
any of these.
