My obsession with Perylene black is no fleeting thing. I love this colour. I want to paint everything with Perylene black. It's in every aspect of my life; I'm surrounded by it at home, I wear it constantly, I always look for it and I've even died my hair the same dark green. It's Gesamtkunstwerk. There's something about it that, I feel, lends itself to the figures and narrative (I use this word with hesitation as I know narrative paintings have often been looked down on as the lowest form of painting!) of my work, it enhances everything. 

 In a way, my use of a single colour as a base for my work, is similar to Picasso's Blue Period, in which he used a mainly monochromatic palette of blues and blue-greens. Art historians aren't agreed on when exactly this period began, but it's generally believed to have been in Spain in the spring of 1901, or during the summer of that year in Paris. The work was inspired by a trip Picasso took through Spain, and the suicide of his close friend Carlos Casagemas, who publicly shot himself in l'Hippodrome Cafe in Paris in the february of that year. The melancholy characters included in Picasso's work of this time were generally prostitutes, beggars, drunks, female nudes and mothers with children. Blindness was something that he often returned to, like in his paintings 'The Blindman's Meal' and 'Celestina', maybe signifying a lack of something, or a sense of hopelessness. 

My favourite works by Picasso are actually from his Blue Period, like his 'Child with Dove', and 'Girl in a Chemise'. 
Pieces from his Blue Period are his most popular paintings worldwide, so maybe there really is power in a single colour, maybe it just has an affinity with people, maybe it's stronger emotively.
