Q: Are the Islamic Legislative Garments for women restricted to being black (in color)?
A: It is obligatory on the woman to avoid wearing garments specific to men. Ibn Abbas; “Allah’s Messenger -sallahu alayhi wa sallam- cursed men who wore the garments of women, and women who wore the garments of men.”
Therefore, pertaining to her clothing, she should not resemble men. On the contrary, she wears what is customary to the women, from red or another color, that does not resemble mens’ clothing. The important thing is that she does not resemble men, (as for other colors besides black) there is no preventative from that inshaa’llah.
