I guess what was/is throwing me is why are you editing the team name color on the banner. They default to light grey which, depending on how big you're emulator screen is, probably won't give enough clarity/detail to distinguish between white and light grey. Certainly white can "pop" a little more but given the effects on the game, it doesn't seem worth it. That light grey may be used in another area of the game graphics. It's no different than if you change a team's skate color, it affects the floor color on the player bench. With team banners, you should really only be editing the top and bottom colors to match (as best as possible) to the team's primary colors.

You'll notice that the first color of the 16 color swatch is the rink color. Per the pink warning/disclaimer, don't use it. Use color #2 as it is the closest you get to white.
