Vision Models

Researchers find that changing text color can hijack a vision-language model's reasoning

A new research collaboration has found that the color, contrast, and brightness of text can quietly steer the outputs of vision-language models (VLMs), causing them to misread meaning and reach different conclusions without any change to the words themselves. The authors say their experiments provide a systematic analysis of how low-level visual styling of text distorts the semantic representations inside a VLM's vision encoder, and how those shifts show up as behavioral changes across both sub
