Color isn't the only thing that defines a good quality RIR. Just because a bird is simply dark doesn't make is "show quality". The standard does call for rich, deep mahogany color but there is a lot more to it. Your bird is not particularly light in color, however I see a number of things wrong with your bird. First of all, her type is off. She should be more deep bodied and have a much more pronounced breast. RIR should have a "brick shape" to them, as they were originally developed to be dual purpose birds. Her comb looks like it has far too many points and they don't follow an even progression of size. Her legs look pale and washed out, almost white, they should be a bit more yellow. Her tail angle is too high, it looks like about 25 degrees when it should be more like 10 degrees. Her tail could also probably be a bit more full, also. Sorry she isn't show quality, she looks more like a production quality red to me. While I am sure she is a great pet and layer, she probably wont do anything for you in a show hall or in a breeding pen.
