Camille Pissarro, "The Artist's Daughter"

Camille Pissarro, Portrait of the Artist's Daughter, 1872; Yale University Art Gallery.

This beautiful Pissarro — detailed and impressionistically naturalistic — has been turned bright yellow in the modern reproduction shown below, removing a lot of detail, obscuring the life-like elements of the portrait and in general adding new coloration without apparent reason. Sadly, yellowed images of famous paintings are common online. It's especially frustrating when a first-hand photo is easily available at a museum's website. Why the yellow? It remains a mystery. Note the watermark of the commercial art vendor on the altered image. It's hard to tell if the real-world reproduction looks exactly like this, or if the image has been further edited during its online history. The photo above comes directly from the Yale University website.
