Shade
Appearance
Shade is produced when the sun is shining and an object, a tree for example, blocks the direct sunlight so that it cannot reach a certain spot. The dark image which the object casts on the ground (or on another object) is called shadow, not shade.
Shade can also mean a darker or lighter color of the same base color. For example: in a picture of a tree's shadow, the grass in the shade will be a darker shade of green than the grass out of the shade.
