Running until April 9, Here Comes the Sun showcases over 20 acrylic and collage works across the late British artist Terry Frost's 50-year career.
The abstract hard-edge paintings contain traces of figurativism, with the coastline, sun, moon and glittering water, as well as boats and the female form, taking the form of free-floating color patches.
"Terry Frost's works are colorful and cheerful, giving a sense of hope, joy and infinite positive energy," Hui said. "His life is equally inspiring."
Frost went through some hard times during World War II, when he served in the Middle East and was captured. Being an abstract artist with seven children to support after the war was not easy, Hui said.
"Life's a bowl of cherries" - a quote reflecting this positive spirit - is printed on the gallery's wall. "Frost's works are refreshing, and the colors will give the audience a great deal of positivity and happiness," Hui said.
