T.T. Yen’s paintings talk incessantly about difficult to express emotional turmoil deep in the viewers' hearts. Starting from his early semi-figurative work, his painting style gradually became purely abstract; and from rigorous aesthetic expression, he gradually developed his bold and heroic vision. This especially can be seen in his exquisite, mature recent work Black and White Series. Yen's wife, Grace Yen, loves using flowers as a creative theme for her work. She feels the inspiration for painting is inexhaustible and can be found everywhere in everyday life. The collaborative work the Yens presents has both sense and sensibility, and reflects their mutually supportive and mutually loving relationship.
