Wilting away: Van Gogh’s legendary sunflowers are turning brown

After 150 years of blossoming, the flowers are slowly turning brown.

Why Van Gogh’s paintings are fading to white

Belgian scientists have revealed a refined explanation for the chemical process that’s currently degrading Vincent van Gogh’s famous paintings, which are losing their bright red. Like other old paintings, van Gogh’s works are losing their saturated hue because of the interaction between red led and light. Using sophisticated X-ray crystallographic methods, the researchers identified a key carbon mineral called plumbonacrite in one of his paintings, which explains the process even better.
