how does fitzgerald use details of a setting and imagery to establish a mood in the opening pages of chapter 2?

Fitzgerald uses details of setting, for example symbolism to establish a drab and gloomy kind of mood. Fitzgerald uses things like "desolate area of land" to try and create an effect on the reader that will make them uncomfortable. In this specific example where Fitzgerald uses the word "desolate" it gives the scene a sense of space and allows it to show the reader the perspective of the mood and the scenery as if they were living in it. Another example is how fitzgerald uses color to bring a sense of gloominess across. He tends to write about the color grey alot to try and convey a sense of gloominess and depression to the reader.
