Cross pollination has nothing to do with it. It would only affect the
color of the plants grown from the seeds of the pollinated flower, not
the flower itself.

Some roses will produce "sports"i.e. different colored flowers on the
same
bush; these are either reversions or mutations caused by the unstable
genetic makeup of complex hybrids. They are not the result of cross
pollination.

As others have pointed out, growing conditions can also affect flower
color.
