Charles Walsh is an abstract painter who lives and works in Northern Ireland. His paintings generate visual sensations through colour and form, systemic structure and repetition. The works are to be seen as contemplative, aesthetic, sometimes austere in their simplicity. An essential part of his practice is in the facture of his own paint from pigments and oils. A major part of his earlier work dealt with the subtle variations of monochromatic colour, whilst more recent works focus on polychromatic saturation. The predominant, recurring theme in all the work is 'the square'. Strategic use of the intrinsic geometric element generates meditative reflection.
