A Grey Day
Williamson was born in Liverpool. He began painting in oil but by 1865 he moved to watercolour. His previous works paid meticulous observation to detail, although he was never associated with the Pre-Raphaelite movement. Williamson sketched his landscape subjects with freedom and spontaneity. He discovered that watercolour could produce broad effects of light and atmosphere. He experimented with placing vibrant patches of colour on to moist paper to allow the different shades to blend together. This technique created a natural and effortless feel to the composition.
