Masking multiple colors

[Orwell]

For a video project, I'd like to apply a plain b/w effect, and then slowly add in colors one by one. Or else at the very least a range of colors, if just as bare as red, blue, and green. Here's a decent sample of the source I'm working with, so I think it'd be at least somewhat viable. There really isn't much color shadowing, its mostly blocky and the scenes that do have it I can cut around, I hope.

Any thoughts on how to go about this?

color pass. It's an amazing effect. creative cow had a tutorial i remember readoing once on it. It's rather simple to do too.

Color pass works great, for a single color. How would I do multiple ones?

looking through creative cow's archives sucks - I can't find it. All I remember is that the example they used was of an indy-style race car that they color passed with both red and blue.

But it applies a B/W filter, so whenever you layer it, you still only get one color.

Hmm...you could create on layer in color over top of a black and white layer, chop it where you want the colors to change on, then just keep adding color keys or whatnot to newer clips...

yah - the only way it works is if you use the "reverse" option and take out the colors you dont want. Its touch and go and masking or Noob's crop method may be better depending on what you want.

heres a quick example
