Yeah, I agree. The blue matches Stargirl better. If Birds of Prey could get off this wiki for having little to no relation to the Arrowverse and Barry Allen finds his way to the new Earth-2 and gives Courtney a modified extrapolator so that she can be a new other-Earth hero to star with the Earth-Prime heroes in annual crossover like how Earth-38 Kara did with the Earth-1 heroes and that necessitated a merge, that blue can be used. Though after Crisis, we might have to be more cautious around crossovers with TV shows not from Earth-Prime.
