Is there any need for you to colour your hair? What is the reason?

For your information, khizaab (colouring of hair and beard) is allowed for white hair and beard. One should abstain from black colouring. One should never do it to immitate the celebrities as well. At times something permissible may be prohibited if done to immitate kuffaar and fussaaq.
