Rubén Hernández 18 artworks | 1 Sold Follow Contact Rubén I am a Spanish architect and artist living in Sydney. In the drawings I show you I try to explore the possibilities of the chromatic economy. I use only ink pens of limited colors: black‚ red‚ blue‚ green and not much more. Drawings are made only with lines in two directions or sometimes scribbles. I have already made a couple of exhibitions in Madrid.
