The works of Ilona Griss-Schwärzler emerges the observer into an intense and excessive world that is bursting with colorfulness and embodies expressive human emotion and love of life. The reddish coloring of her feminine portraits attract attention and next to reds the artist applies intense yellows and azure blues which evoke strong emotions and convey vitality. The dynamics of her work is enforced through collage techniques and through incorporating letters, buzz words and sayings into her paintings, which identify her roots in the Bregenzerwald in Austria.
The novel of Hermann Hesse inspires Ilona Griss-Schwärzler to a large extent, where a young man called Goldmund continuously seeks for the primordial mother. Repeatedly Goldmund leaves friends and loved ones and wanders around the country side. His desire for life, love, passion , situations of danger and his longing for his mother, the feminine archetype drive him further and further.
Ilona Griss-Schwärzler is an evolving seeker, who attempts with her artwork to combine form, color and drawing in an optimal way. With a repeated effort she tries to capture artistically within her feminine portraits moments of real human passion and mirrors these snap shots of various emotional shadings back to the observer.
