can a bride demand her female relatives to wear color themed dresses to her wedding, or is it a problem of chukas hagoyim?
Answer:
While her right to demand may be questionable [requesting might be a better idea], there is certainly no problem of chukas akum. That prohibition is limited to things which have no rational practical reason, and hence are just a form of non Jewish practice. Wearing color coordinated gowns is a reasonable practice to add simcha and elegance to the wedding.
