Her most recent solo exhibition, Color Chords at MUSE Gallery, featured paintings that explore the analogy between color-guided composition and musical expression. She works on wood panels, applying oil paint in layers, and blending them to create new hues. Like musical chords, where tension between different tones is resolved by their participation in the whole, Lachman composes harmonious paintings by carefully selecting color notes. Her intuitive approach complements her years of teaching color theory at Penn Design at the University of Pennsylvania where she earned her BFA and MFA.
She is a member of the Muse Gallery in Philadelphia. Her paintings are represented in numerous private and corporate collections.
