    Which effect? BGs are CG environments with actors shot on greenscreen to lay over them. The color amongst B&W is also keying and working with mattes but AE has a quick simple solution called ‘leave color’.

    If you plan it right it doesn’t need intense rotoscoping. If you can isolate a colour then you can just garbage matte the rough area around that object and use the leave colour effect, then adjust the hue on the result if you want to alter the colour some more.

    Some of Sin City, particularly Nick Stahl’s yellowness, was done with keying; by painting him blue, which doesn’t have any green tones, they could key him independantly of the greenscreen and then shift the colour to yellow.

    If you have Color Finesse then it is worth exploring the “secondary” tab. This allows you to select a range of colours rather than a single colour – more powerful than the leave color filter. Color Finesse does take a bit of learning, but it is definitely worth it.

    You can also isolate/effect a range of colours with the hue-saturation tool. Instead of instantly putting saturation down, pick from the drop down list “blues” or something, then you can adjust the range to whatever you like.
