His approach relied on geometric precision and spatial tension. Booth used diagrammatic sketches to plan his compositions, ensuring every line had a purpose. In works like Transverse and Surprise, he used flat planes of colour to create depth. He avoided decorative flourishes. Instead, he preferred a clean, mathematical arrangement of forms. This method allowed him to move between figurative studies and total abstraction without losing his technical rigour.

Modern collectors value Booth for his ability to bridge different eras of American art. His prints work well in contemporary spaces because of their clarity and balanced palettes. The stripped-back nature of his figure studies and geometric abstracts offers a calm aesthetic. These pieces provide a sense of order. They represent a disciplined era of modernism that remains relevant for interior design today.
