Hi! Well, "beige" is a french word originally pronounced [beɪʒ]. In Spanish, people simplify its pronunciation and say [beis], 'cause the [ʒ] sound doesn't exist in Spanish. Regards:)

You can say it like beish (beige). I hope help you. I am from Mèxico. Take care.

类似这个音：掰衣嘿。重音在 掰 上，g直接跟e或i，g发h的音，gu跟e或i发g的音。
