It's normal to have some die off, and corals can turn white when they die. Check your water parameters, especially ammonia/nitrite/nitrate and salinity. Post them here when you do. Also let us know about your tank (age, occupants etc.) in your sig. That can help a lot.

Do you mean green and purple coralline algaes? In my experience it usually takes 8-12 weeks for the coralline to start growing when the rocks are placed into a new tank, even if the rocks are "cured". When a rock is taken out of water and exposed to air, even if only for a few seconds it still damages that life, and there will be a certain amount of die off just from that alone. Your system will have to age a bit before the coralline will start to grow, in the meantime some of it will bleach out (die) to white. Just be patient, it'll come back.
