Pure Color is a commentary on television media in Hong Kong – colorful, fast, unstable, and superficial. It is also an exercise of introspective interrogation through the converter lens, which in turn is viewed through the camera. Converting a reality that defies all representation, a reality that is based on manual instrumental means, a series of action and reaction that carries no intention or high hopes, a mediated reality.

《純色彩》嘗試就香港電視媒體作出評價：色彩斑斕，快速不穩定以及表面化。使用變焦鏡作內心審議，運用攝錄機轉變視線，展現沒法表彰的現實。經人手操作的儀器製造出來的真實，一系列沒任何動機或盼望和反應，只是個被媒體化的現實。
