Help with Wedding Party Colors!!!

I have been struggling hard with deciding a wedding party color scheme. My wedding theme is timeless and elegant, and roses are a MUST, so I was leaning towards red bridesmaid dresses, bouquets with red roses and baby's breath, groomsmen in black suits and red ties, and gold accents sprinkled in subtly. Firstly...do you think it will look nice? Secondly...my mother and junior bridesmaids don't look good in red or gold (they're pale redheads), so what should I have her wear? Also open to new color scheme suggestions that look timeless and elegant!
