The only noticeable differences when color is considered are the variables related to quality and public acceptance. Otherwise in the area of quality the deeper or richer the color tones the better. In effect, the less weaknesses you can see the greater the chance that no hidden deficiencies in mind or body exist. It is however sheer foolishness (to be a gentleman about this) to say that one color is any better than another with one exception: the physical deterrent affect on the outsider. The blacks and reds are immediately recognized as a DOBERMAN. Next are Blues, and last, but never the least, the Fawn (because most of the world has never even heard of a fawn).
