Don't sweat it! Usually luxury brands handle very beautiful shades, and even if the shade of pink is more light, I think that actually could work in your favor, since if the color turns out to be lighter it is actually more neutral, which is always a good thing outfitwise.
And well, I know what you mean, you see one thing, fall in love, order it and then, as if a cruel joke from destiny you run into something that caught your eye as well, I personally think things happen for a reason and if you ended up ordering the pink one is because it was meant to happen that way, and if you're still falling for the red one, perhaps the future holds a beautiful red bag for you.
Sending lots of light your way and the best wish so you fall even harder for your new bag when you see it for the first time
