Janell Moon uses subconscious material in her oil and acrylic paintings and mixed media. Her work was shown in 2019 in the O'Hanlon Center for the Arts, Mill Valley, CA. Her work is poetic and dream-like, breaking objective boundaries by use of color to create form. Moon feels that painting is a broad visual language that expresses content and feelings even if we don't always have the words.

Her one woman show in 2018 at NAID gallery in Richmond, CA was of mixed media sourced from dreams and waking liminal states creating new territories. There is a sense of shadow in many of this work, the shadow that place where the conscious mind works with the invisible undertow of mystery. There are also political pieces and compositions of pure visual interest.

In 2018, she also had a one woman show of oil paintings in Gallery 64 in Emeryville, CA. In 2017, her paintings were featured in Berkeley's Mythos Gallery in a two person show.

Moon had a one woman show at the Frank Lloyd Wright Marin Civic Center Gallery in San Rafael, CA and the Marin Art Gallery Cooperative in Ross, CA where her work was rewarded first place in a countywide competition. Her work has sold internationally.

Her work was shown in group shows at the Berkeley Art Center, Expressions Gallery in Berkeley, Emeryville Celebration of Art, and the Berkeley Art Passage in the arts center in downtown Berkeley.

In 2021, Moon joined the artist hub, Firehouse Artist Studios, on 9th Street and Gilman where she works and participates in all Open Studios with 30 other artists.
