Some of the color terms may be a bit misleading. Let's talk about a few of the most confusing ones for owners:
Red: This is a deep, dark orange which some refer to as mahogany.
Blue: This is a diluted (faded) black. This adds a shine to an otherwise black coat. With deep bluing, the hairs can be described as metallic. One reason why many struggle with understanding this color is because for many dogs, it simply does not show in photographs. And for some, only outside in bright sunlight, will the blue shine be seen.
A true blue Beagle will have blue pigmentation; thus helping to make the distinction between this and a black. Eye rims, lips, paw pads and nose will be blue as well. For many dogs, this will be most apparent on the nose.
Lemon: This is such a lovely coloring on this breed and sure to bring about admiring looks. A pure solid lemon Beagle is very rare. More common is the Lemon & White. As the pure white lemon Beagle puppy grows to an adult dog, the base color will be a pure white or an off-white with light golden patches.
When a Beagle has a mixture of lemon & white, that dog is still often referred to as a lemon.... Technically, he or she should be registered as a parti (lemon and white) or as a solid lemon with white markings. With many dogs, the lemon will be light and dark on various parts of the body.
