I wouldn't worry ...different strokes for different folks. A number of years ago I was invited to have a photograph of a particular piece in the Art in Public Places for an anniversary of that program. I photographed it with 4x5 format and couldn't decide which of four images to use so I spent very many hours to print all four negatives on one piece of paper in the required scale as they were going to have rear illuminated transparencies. Since the tonal separation was very subtle I also took some 4x5 color transparencies at the same time and spent 30 minutes round trip to the local lab. As you might have guessed the person incharge wanted to use the color. I insisted they use the B&W as long as they could be accurately reproduced. I was pleasantly pleased that they used the B&W.
