Abstract expressionist artist Brighart was born in 1956 in Amsterdam. There she did her preliminary training at the Rietveld academy. From December 2004 to 2007 she worked full-time at the WBK Free Academy of Visual Arts in The Hague, where she was taught by Zhuang hong Yi, Mark de Wijer, Vincent Botella, Bill Boogaarts, Peter Otto and many others. She also attended the Willem de Kooning Academy from 2010 till 2011.
In her work Brighart tries to depict the spiritual world in an abstract visual language.
She studied quantum mechanics and string theory and has been inspired by theoretical physics. She also draws her inspiration for her intuitive acts of painting from Sir Karl Popper, who said: 'Optimism is a moral duty' (1993) and Willem de Ridder who wrote the book: Spiegelogie and said "The world is a mirror of yourself."
Red, orange and yellow are common in Brighart's abstract colourful paintings. For example, she experimented with the use of nylon umbrellas (2005); space-gel (2008) and glass balls (2012).
Currently, the artist works with layers of paint, creating transparency: Valley (2010), Higgs deeltjes (2012), Mediterranean sea (2015).
