Not usually, the mother of the bride tends to wear colours that
compliment the bridal party rather then match them.

Colors that complement the bridal party are for example, if the
colors are pink, the mother of the bride could perhaps wear dark
pink, fuchsia, rose. I think you get the idea. Usually there are
two colors for the wedding and so that would open up more choices
for colors to wear for the mother of the bride or groom. You may
