Light influences colors and atmosphere. Monet painted the water lilies and the pond many times at different times of the day. The colors change under the influence of mist, rising or setting sun and the like. Monet has recorded this in his paintings in his own way.
Especially the last period of his life, from 1910 until he died in 1926, the garden and especially the pond with its beautiful lilies was an important source of inspiration.
But when he got older he got more and more problems with cloudy eye lenses, which is very difficult for a painter. When he was 82 he completely removed the lens from his left eye.
