Which act prohibits discrimination based on race, color, and receipt of public assistance income?

The act that prohibits discrimination based on race, color, and receipt of public assistance income is the Fair Housing Act. This federal law, enacted in 1968 and amended several times since, is designed to eliminate discrimination in housing-related activities. It specifically bans discriminatory practices in selling, renting, or financing housing based on various protected characteristics, including race and color.

While the Equal Credit Opportunity Act of 1974 does address discrimination in credit, it does not cover public assistance income specifically nor does it encompass the wider array of housing issues addressed by the Fair Housing Act. The Civil Rights Act of 1866 primarily concerns racial discrimination in property contracts but does not mention public assistance. The Americans with Disabilities Act, meanwhile, focuses on discrimination against individuals with disabilities rather than the broader issues related to housing and income discrimination. Thus, the Fair Housing Act is the appropriate legislation for prohibiting discrimination in the context specified in the question.
