Plugin for single color matte / tinting in footage?

Hello clever creatives,

Just a quick question. Does anyone know of a plugin that one can use in After Effects (or anything else) that will isolate a particular colour (color) in footage and create a matte for just that colour?

I've created my footage specifically such that there is one colour that I want to isolate and saturate everything else.

The only way I can think of doing it currently, is going to take quite a while to do. Duplicating my footage on the timeline and rotoscoping the colour out of the top layer and saturating the bottom layer - blurring it into the footage, etc.

For example, let's say it's a London scene and there's a red bus in the shot. I want the surrounding footage to be saturated and the bus to be as it was shot.

Anyone know of an easier way than rotoscoping it?
Thank you for any help offered.

If the color you want is super consistent, you could use keylight(or any keying software) and choose the color of the red bus to key out. Put a layer below that set the track matte to alpha inverted, that should give you just the bus. Add one more layer below where you crank up the saturation and you have your effect. You might need to blur the top layer a bit to blend the two layers together.

Of course this only really works if the color you are trying to isolate is perfectly consistent, shadows, highlights can all make using this method a real pain. Of course that's why Adobe invented the rotobrush tool.

Good luck,

Thanks for your help, John. In the end, I had to rotoscope it all.
