A hint of light piercing trough darkness strongly attracts me in an image. When it goes deeper than a a juxtaposition of colours, when the theme of the art piece reflects this battle between light and shadows, I am truly hypnotised. Hermenegildo Anglada Camarasa, a Spanish painter born in 1872, produced a few paintings with these qualities. Reminding me about his contemporary Gustav Klimt, I love the combinaison of floral patterns, of white women surrounded by darkness and of evanescent exotic elements.
I have had many of those pictures in my files for so long, I do not remember all the sources... but you can find many of them at Artodyssey.
