The Color Purple embodies the ethos that, despite myriad problems, anyone can find community, love, and belonging—even beyond the margins of society. The mood remains largely hopeful throughout the novel. In large part, this hopeful mood depends upon Celie and her personal outlook as the point-of-view character.
Most of Celie's letters are addressed directly to God. Despite the dire circumstances she often finds herself in, Celie is able to push through and remain optimistic because she believes in a higher power. Celie's strong sense of optimism, hope, and uncompromising faith forms a solid core both within her character and the novel itself, remaining strong and steadfast even in the midst of chaos and pain.
Religion is not the only pillar in Celie's life, however, and her religion does not conform to traditional, orthodox forms of Christianity. Despite believing in a divine power she calls "God," she does not entirely buy into the more repressive aspects of religion—those that would see her and those closest to her shamed for their queerness and alleged sexual impurity. Without the presence of shame to weigh her down, Celie is free to focus on the hopeful sentiments she finds within Christianity—a hopefulness that carries throughout the novel.
