What would be the most likely explanation if none of the tested paint samples had turned brown? 1. The reaction was not actually caused by UV light.
2. The reaction only happens in real sunlight, not artificial.
3. The paint behaves differently on a canvas than it does in a laboratory.
4. None of the tested mixtures matched the chemical composition of Van Goghs paint.
