Can I have colored food after 2 days of teeth whitening?

Hi.. I have done teeth whitening on the 25th of January 2015 and today is 28th of January 2016.. I have already finished 2 days.. My doctor advised me to have food which is only white in color. My question is that can I have colored food now? She also told me to have no colored food for 2 weeks but I am starving myself as mostly I don't like the food what I am eating now. Can you please advise??
