What are the different kinds of lentils?

Lentils are sold in many forms, with or without the skins, whole or split into halves. While the most common types in the United States are green and brown, both whole with skins, lentils are also available in black, yellow, orange, red, and pink colors. Yellow, red, and orange lentils are usually without skins, and sometimes split. The different types offer varying consistencies, with the whole brown and green lentils retaining their shape better after cooking, while the yellow, orange, red, and pink generally become soft and mushy. While the flavor differs slightly among the varieties, they generally feature a hearty, dense, earthy, and somewhat nutty flavor.
