In Gerardo Rueda we can appreciate the coinciding of lyricism with strictly geometric construction; the geometry highlights the emptiness. What he does in Pintura blanca is to mark, to point out the empty space, adding an element of collage to it and producing a play of shadows on the white background.
We have seen the compartmentalisation of space in the work of this artist from the beginning. In the mid-seventies, he was already doing this on wooden structures with rigorously straight forms. Although he initially tends to make a picture symmetrical, he usually introduces variations that break the symmetry, so that in this sense Pintura blanca constitutes an exception.
