It is difficult to answer this in terms of the colors we see, because a bee's colour vision is different to our own. A bee's colour vision extends well into the ultra-violet part of the spectrum, which we can't see at all, and it doesn't extend so far as ours into the red end of the spectrum, so they wouldn't be able to see a deep red.
Because of this, bees see flowers differently from ourselves. There are patterns and stripes which can only be seen in ultra-violet which are invisible to us, but to a bee are guides to the nectar.
That said, bees are attracted to flowers of all colours. All that matters to them is that they can get nectar.
