bibliography with three critical sources

Hi

Actually The assignment is based on (Walker, Alice. The Color Purple.  (1982). New York: Harcourt, Inc., 1992). So, you need to write a bibliography about the them below and the most important part is to support it with three critical sources. Finally, please Be sure to provide more details in order to make the bibliography in a good standard form..

Here is the theme from the Novel:

Color

Shug is often described in colorful terms:
she is rouged in the photograph Celie first sees of her and twice wears
seductive bright red dresses during the course of Celie’s records. She also
gives Celie yellow fabric for her quilt. These bright, exuberant colors are
full of energy. Contrastingly, the clothes Celie is able to choose from when
she goes shopping with Kate are brown, maroon, or navy blue because Kate
doesn’t think Mr. ______ will want to pay for her preferred red or purple
because they look “too happy.” When Mary Agnes first starts writing
her own songs, they are songs about color: “they call me yellow/like
yellow be my name.” As she tries to find her identity apart from her skin
color, Mary Agnes explores the shades of color that lie beneath her skin, in
her personality–finding these colors within gives her the voice to sing.

When Shug and Celie discuss their idea of
God, Shug explains that God is in everything and that God is the beauty in
nature. Shug points specifically to “the color purple” (traditionally
a color of royalty) and wonders how such a color could grow naturally. Purple
seems rare in nature. It as though the color itself were a manifestation of
God.
