Catou has dedicated many paintings to Colonia del Sacramento, Uruguay, this sleepy city on the banks of the Rio de la Plata. Founded in 1680 by the Portuguese, it had spent the centuries tossed between the colonial ambitions of the Portuguese and Spanish empires. Today, Colonia, with its worn cobblestone streets and old colonial house facades, offers visitors a serene, almost metaphysical face. Fleeing the frenzy of Buenos Aires, she found herself confronted with other colors, all in nuances, with pastel tones, while she painted, most often, canvases in bright colors. Catou wanted to convey this unique sensation that she felt in this place, that of suspended time, as if it no longer existed. Obsessed with colors and textures, she wanted to capture the very essence of Colonia del Sacramento. In some places she observed how the evening light transformed the walls into living paintings, where the shadows danced in the wind. It was a period in which she declined Colonia not only in her canvases, her miniatures, but also in porcelain painting where all the shades of blue helped her to represent the melancholic atmosphere of this very small town.
