Goodwill ambassador of gay art

Sun launched Sunpride Foundation in 2014, with the hope of effecting social change by showcasing LGBTQ+-themed art collected from Asia. He reckons artists often have reservations about the "gay art" label, when they ought to wear it with pride.

Coined by fusing the words "spectrum" and "photosynthesis", Spectrosynthesis alludes to the spectrum of light representing the diverse and rainbow-colored LGBTQ+ community.

Both exhibitions hosted works by more than 50 modern and contemporary artists from around the world, including the likes of Hong Kong's Tseng Kwong-chi and Jes Fan, as well as Xiyadie and Yan Xing from the Chinese mainland. Artworks either featured LGBTQ+ subjects or were created by LGBTQ+ artists. The themes ranged from same-sex parenting, social stigmatization of non-binary sexual relationships, equality, culture, self-identity and more — ideas that anyone, queer or not, could relate to, says Sun.
