Jing Wong teams up with Marco Mak, hires every famous actor he could find (Anthony Wong, Jordan Chan, Francis Ng, Gillian Chung, Ching Wan Lau, they're all present) and throws them into a comfortable genre formula that is known to work well and can be produced without too much hassle.
Colour of the Truth is easy genre cinema, but backed by a movie making machine that is known for its incremental refinement and can deliver quality on routine alone. There's a plot about revenge and deceit that leads to some inevitable stand-offs, but if you've seen a couple of these films you should already be aware of that.
It's hard to find obvious flaws, the only negative here is that nothing really jumps out. It's a fine production, but safe and expected. Solid pacing, a good cast, some visual flair and enough genre pandering to please both action and crime fans. I had a lot of fun with this one, but it's for genre fans only.
