A posing trunks anomaly

The same bodybuilder can be seen in both pictures, but unfortunately, I don't know his name. Based on the background, the two photos appear to have been taken at the same competition, and the competitor's number is also the same. However, the color of the posing trunks is different. It might just be an optical illusion, perhaps the photos were taken with different cameras, or the guy might have competed in two different categories at the same event. I don’t know the reason for the two differently colored trunks, but one thing is certain: it’s the same dick in both, pointing in the same direction as well (a 7 o’clock type VPL).
