Thanks Radar. I went with red coats and breeches, white hats and sashes, and green ribbons at he calf and hat band. I chose those colors for the reason above, a French Queen, so white seems appropriate, and green ribbons because in later years many countries equated green with Queen's regiments. They really look pretty good too, and quite different from my King's Regiment in red coat, breeches and a darker red hat, with blue ribbons.
