Cross Country / Eventing (Militaire) / Racing colours
Red on right, white on left, and whatever crazy colour combination you want in the middle. (Isn't that how it goes?) Dress the horse first, then add the unmounted rider and add helmet colours and crash vests. If you just want to try out colours of riding apparel, you'll find another unmounted rider "model" down the page with the clothing selections, to save you having to scroll.
IMPORTANT: To save your image, you need to do a screen capture.
