The Normal to the right shows some ochre/orange color on the arches at the edge where the body fur meets the belly fur. It is not nearly as vibrant as the standard requires.
	The Opal to the left lacks the ochre/orange color at the edge of the arches where the body fur meets the belly fur. At best, there is only a hint of color. Note also the lack of definition to his dorsal stripe. On his head, you can only see a hint of the stripe instead of the "soft dark grey stripe" required by the standard.  His markings are too pale.

Winter Whites The agouti markings on Winter Whites are similar to those on the Campbell's. One difference is the dorsal stripe. The dorsal stripe on a Winter White should be wider than that on a Campbells. Another difference is in the arches. The agouti Winter Whites have ticking in the area under the arches while the Campbell's do not. And the Winter White Normals and Sapphires do not have the ochre/orange color at the edge where the body fur meets the belly fur. Lastly, the arches are more clearly or easily defined on the Winter Whites.

This Winter White is far better than the one below. You can see the distinct arches on his side. The ticking in the white area under the arches is even. You can also see his dorsal stripe. Note that the dorsal stripe is wider than that on the Campbell's dwarves. This is one of their distinguishing features.
	This picture shows a Normal Winter White with poor markings. Note how dark he is. The ticking in the area under the arches is too heavy making the arches hard to distinguish. Even his dorsal stripe is hard to see with all of the other black.  His markings are far too dark overall.

Another hallmark of the Agouti hamster is hair banding.  Classically, each hair has three distinct zones - the tip, the middle area and the section nearest the skin.  This particular photo is of a Normal Campbell's dwarf. The Winter White agoutis have the same hair banding. Of course the color depends on the color of the animal.
