I think it's a personal preference. If you like black with PHW, then it should be a good & safe buy for you.
Black is a basic color. So, one can never go wrong with black.
If you had asked me that one year ago I would have said yes without any hesitation. But now, after looking at all the beautiful colors H has, I would say perhaps you should consider a color instead. There are many lovely black bags by other fashion houses, but no one does color quite like H! Something that would be timeless yet still matches with all your stuff, maybe a gold, or etoupe or gris T? Something different yet a safe neutral that you can get lots of wear out of!
I love black and if it is going to be my one and only birkin, I will go for it!
