All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
Your husband has the right to ask you to wear a Hijab that is free from attractive colours when you go out to a place where non-Mahram men can see you. The scholars stated that among the conditions of Hijab which a Muslim woman wears when she goes out is that it should not be a beauty in itself as we clarified in Fatwa 83702.
Having many colours on the Hijab renders it not fulfilling its purpose which is to prevent men looking at the woman. The Hijab that is full of colours is beautified with those colours and the woman becomes a means for men to look at. Allaah Says (what means): {…and not expose their adornment except that which [necessarily] appears thereof.} [Quran 24:31]
It is not permissible to wear this kind of Hijab neither when the husband is absent nor when he is present.
For more benefit, please refer to Fatwa 82314 and 87398.
Finally, you should praise Allaah who blessed you with a husband who loves you and is jealous over you.
Allaah Knows best.
