Red or Black moh Dress

I’m getting married next year and I have 5 bridesmaids and 1 MOH. Our color scheme is dark red and black. I decided to have my bridesmaids wear dark red/burgundy dresses but in a chiffon material (any style they want) and I would like my MOH to wear black to stand out but I’m not sure if that would look nice? Any thoughts or advice would be great, thank you!
