The various shades allow each artist infinite dialogue possibilities, leaving open countless visual games of the most diverse natures. It is true that each color provides great power on their own, but it is also possible to combine them in diverse impacting ways. Gui Calil draws on colors in imaginative ways. A common feature of his works in acrylic on canvas is their aesthetics and poetry, established on exploring the freedom provided by space, related to his work tools. Each work has something to communicate, displaying a specific relationship with reality. It is as if each new canvas dialogue with the viewer in a unique manner, but within a greater project, where one of purposes is to allow and encourage emotions to surface. At the first moment, the impact is what counts. It is impossible not to react to what Gui Calil features.

The paintings function as a great family. There are blood bonds between them, but also great differences in atmosphere and personality.
