In the piece II of the series Paso sin ver (Passing without Seeing), which came to form part of the collection in 2015, Aranguren creates complicated mazes with lines that cross each other in apparent chaos, nevertheless maintaining harmonic rhythm, while she reserves a part of the space to show the silence of monochromy. The linear action finds its counterpart in the space’s lack of color and nothingness. This painting contains the paradox that envelops all of her work, and which arises in that alternation between calculated balance and the expressive power of feelings. The work symbolically represents her indignation towards people’s blindness to world problems, the central theme of the series presented in the exhibition that took place in the museum in 2011.
