Aleksandra Jachtoma's abstractions are an atom consisting of light and color. The process of artistic work does not consist in gradually covering the canvas with individual structures, but in the overall creative act that immediately absorbs the entire surface of the painting. The most important is the color and its vibrating effect down to the depth of the image plane.

The intensification of slightly hazy colors takes place thanks to a specific light, the source of which is located on the plane of the image.
