Hi Michele - first: a belated
I could very well be mistaken! I do not grow 'Barbra Streisand' (yet)
so my opinion is only based on photos that I have seen and now that you mention that the colour, I really don't know.
Maybe
@zuzu, Zuzu who grows this rose could comment.
There are a lot more photos on HMF -

Have a look, you would be the better judge having seeing the blooms in all stages.
Also come and join us on the rose forum - we would love to see more of your roses
