Some leaves are in the shade because light is blocked by trees.
A dozen different species of plants growing in the shade

Shade is the blocking of sunlight (in particular direct sunshine) by any object, and also the shadow created by that object. Shade also consists of the colors grey, black,white, etc. It may refer to blocking of sunlight by a roof, a tree, an umbrella, a window shade or blind, curtains, or other objects.

Shade is an important issue in temperate and tropical zones for providing cooling and shelter from the sun. Providing certain configurations of shading is an important passive solar technique. This may be done with overhangs, with shade trees, or with vines. Vines particularly suited for this purpose include Boston ivy, Virginia creeper, and morning glory.

Shade offers relief to golfers and sportsmen of many types. Careful consideration must be taken when removing trees near tees and other clog points on a golf course routing. It has been shown that the shade from a natural tree can be several degrees cooler than that provided by artificial structures or umbrellas.

Shading using non-living materials blocks the sun, but also results in sunlight being absorbed and re-radiated as heat, or in sunlight being reflected as glare. Green plants, on the other hand, not only absorb a significant portion of the sunlight to invest as energy in photosynthesis to produce sugar, but also actively transpire, producing an additional cooling effect.

In gardening terms, there are various types of shade:

  • Full sun - more than five hours of direct sun per day.
  • Part shade - two to five hours of direct sun, or all-day dappled sun (sunlight shining through open trees).
  • Full shade - less than two hours of direct sun per day.

Simple English

A place is called in the shade when the sun is shining, and some object, a tree for example, blocks the direct sunlight. So the sunlight can not reach the 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.
