Lucie was born in Truro. She studied at Falmouth and Wimbledon Schools of Art. She lived in St Ives, Cornwall, and painted seascapes in situ on the beach using a special white tent to reduce the glare of sunlight on her wet painting boards. Having painted predominantly in oils, in 2011 she began using acrylics for large scale works. This is something that allowed her to paint quite quickly reflecting her "all in one go" approach when painting out of doors.

Lucie's first solo exhibition was held at The New Craftsman in St Ives in 2011. She exhibited in many mixed shows and in the Affordable Art Exhibitions in London. She died in Camborne, Cornwall following a long illness.

Her parents, Heather and the late Barry Bray, were also artists.
