《紫颜色》是美国非裔女作家艾丽斯·沃克的代表作。小说不仅表达了其对于“非洲之根”的认同,更体现了对于非洲异邦的疏离感。因此,艾丽斯·沃克的民族意识呈现出既带有种族性又带有美国化的矛盾特质。这种矛盾的民族意识表明,沃克对于“非洲之根”的探寻是为非裔美国人在主流话语中争夺话语权,谋求平等的社会地位以及为美国多元文化的融合共存所做的努力。 “Purple Color” is the representative of American African American writer Alice Walker. The novel not only expresses its recognition of “the root of Africa ”, but also reflects the alienation of Africa’s foreign state. Therefore, Alice Walker’s national consciousness presents the contradictory nature of both ethnicity and Americanization. This ambivalent national consciousness shows that Walker’s search for “the root of Africa ” is an effort to fight for the rights of African Americans to speak in mainstream discourse, to seek equal social status, and to coexist in the United States’ multiculturalism .
