Marriage in Islam is primarily intended to protect one’s chastity by guarding against fornication, and thus enable each other to build the foundations of a happy family. These principles are fulfilled only when the parties enter in to marriage with full consent, on their own accord, without any external pressure. It is, therefore, important for people to choose as marriage partners those with character, moral integrity and faith. The role of parents in marriage of their children is limited only to ensure that the latter make the right choice. The Prophet, peace be upon him, said, “If a person of pleasing character and faith comes forward as a suitor, accept him/her; otherwise, you are opening door to corruption.” It is therefore imperative that parents agree to marriage once these criteria have been fulfilled.

You have therefore every right to marry the person you have chosen as long as the above criteria are fulfilled. Your parents’ objections based on color, etc. are clearly not valid. I advise you therefore to approach your parents again either by yourself or through wise people in the community they trust to change their minds.

If they are still persistent in their refusal, you have the right to marry the person you choose. In this case you should ask the next closest male relative to give your hand in marriage on your behalf; if no one is willing to do so, you are free to delegate someone as your representative and get married. Marriage performed in this way under the above circumstances is considered as perfectly valid in Islam. 

Having said this, however, I must also point out that you should still seek to establish good relations with your parents. May Allah inspire us all to speak and act rightly-aameen.
