Those RC35's look to be in good shape and if you are going to put them on this I think you are right to stick with the black frame if it's going to have orange writing maybe add a few other orange touches.
Continental did a few MTB tyres with an orange stripe down the middle, coloured tyres are one of those marmite things I think but personally I love 'em!
