Green means go. Yellow means caution. And red means stop. Small wonder that some industry observers have decried the tendency of many real estate websites to rate schools — which are reportedly treated by some as a proxy for local racial makeup — with traffic-light colors.

- Zillow Group made the change in part "to reflect that GreatSchool ratings alone do not define school quality."
- The National Fair Housing Alliance is evaluating whether neighborhood data steers people away from neighborhoods with high concentrations of minorities.
