His canvases and papers give boundaries to this universe in which multiple strokes and forms channel the interpretive strength of the artist. Without forgetting the prolific treatment that the colour receives in all his work, we must highlight the prominence that the black manifests in the evolution of all his work. In some series the black harmonizes as a background with the strokes and graphics of the rest of colours, in others, black is the stroke and graphic design. In the most daring pieces, black becomes the only representative colour to bear all the expressive load of the piece. Ruz’s work is vital and consistent, represented with his sincerity and tenacity. It is a contemplative experience through which the artist lives and interprets life. The result is a mysterious and evocative gift full of beauty and harmony.
