Kulchytska’s work is renowned far beyond the Ukrainian art scene. She created art in diverse media and on varied themes, highlighting her originality and progressive vision. Her oeuvre includes oil painting, drawing, graphics, illustration, watercolor, tempera, etching, woodcut, linocut, and enamel, reflecting a consistently multifaceted practice.

All of Kulchytska’s works express deep love for Ukraine and its culture, often striking viewers with her vibrant color choices. Her imagery conveys a zest for life, gentle warmth, and joy through harmonious color compositions.

Kulchytska’s etchings, woodcuts, and linocuts helped bring Ukrainian painting closer to European artistic traditions. Her watercolor albums, Folk Architecture of the Western Regions of the Ukrainian SSR and Folk Costume of the Western Regions of the Ukrainian SSR (over 100 illustrations), hold great artistic and scholarly value. Having traveled extensively on foot across western Ukraine, she painted from life. In her works — whether carpet ornament sketches, enamel, bronze, or majolica — she conveyed her vision of the Ukrainian people’s spirit.

For a time, Kulchytska lived in Przemyśl, where she taught in local gymnasiums as a professor. The Kulchytska family home (belonging to Olena and her sister) became a hub of artistic life. She was also a co-founder of the Stryvigor Museum in Przemyśl.

Her works have been exhibited in numerous museums worldwide. The National Museum of Sheptytsky in Lviv published a complete catalog of Kulchytska’s works, including 347 reproductions of her graphics, paintings, and applied art. Over her lifetime, she produced more than 4,000 works, many forming part of the golden heritage of Ukrainian book illustration. She also authored memoirs, Chronology of Creativity. Kulchytska dedicated her life entirely to art and did not marry.
