Wong Yau is a Singaporean watercolourist dedicated to preserving local history through art. After a 40-year hiatus, he picked up his brushes again in 2018, rekindling a youth passion. While he initially painted only on weekends, his retirement in 2025 has allowed him to dedicatedly paint three times a week.

Having received formal art training as a teenager, he continues to refine his craft by studying watercolour masters online to master the medium's subtle complexities. His paintings focus primarily on traditional local buildings and heritage street scenes. By utilising a masterful play of light and shadow, he creates striking contrasts, employing bright, vivid colours to inject energy and vibrancy into every piece.

Through his artwork, he aims to document and celebrate the architectural legacy and historical narrative of the region. He regularly shares his evolving portfolio with the community online.
