If I were into gaming, and I had a horse that looked good in blue, I would use this. It is not overdone. The blue accents are restricted to the seat, insides of the stirrups, and corners of the fenders. The accessories are also blue. This does not look bad.
Here is another example of a not-so-horrible one...
Ugh, I think I may be ill. Not only can you tell that it is a cheaply made synthetic piece of junk, (now I am NOT badmouthing synthetic saddles, I own 2) but the color scheme is atrocious. The blue nylon accessories are not even the same shade of blue as the saddle. Oh, and dig that "buckstitching". If the saddle were black and blue or black and green, it would be tolerable. My horse would hide her prissy little head in shame if I put this monstrosity on her.
