Researchers have explored how vision encoders within vision-language models (VLMs) represent conceptual information, using canonical color as a test case. By analyzing how well canonical color could be decoded from both color and grayscale images, they found that this conceptual information remains accessible even when color is removed from the input. Further analysis with full VLMs indicated that post-training can significantly impact color decodability in the vision encoder, suggesting canonical color is a useful tool for understanding conceptual semantics in these models.
