The visual style of Wong's films is key to his work, often described as beautiful and unique. The colours are bold and saturated, the camerawork swooning, resulting in what Brunette calls his "signature visual pyrotechnics". One of his trademarks is the use of step-printing, which alters film rates to " hard blocks of primary colour into iridescent streaks of light." Other features of the Wong aesthetic include slow motion, off-centre framing, the obscuring of faces, rack focus, filming in the dark or rain, and elliptical editing. Stephen Schneider writes of Wong's fondness for "playing with film stock, exposure, and speed the way others might fiddle with a script."
