Final cut pro help - get just ONE colour to show in a shot, urgent!

[TheSVD]

Hey guys, im currently editing my coursework with FCP.
The film was shot in colour, and i have made it all black and white.
There is one shot, however where a silhouette is smoking a ciggarette in front of a TV. As the person drags on the ciggarette, i love the orange glow it gives out! Is there any way to have that shot completely desaturated, apart from the orange glow of the ciggarette?
FCP noob here btw :o
Thanks guys, would appreciate help pronto cause i wanna get this done tonight :D

Google "final cut pro pleasantville effect" and you'll get a ton of hits outlining how to do that.

Within finalcut pro you can use two methods probably best to use in combination.

One is the Effects/Key/Chroma keyer to color out as much of the color without losing the orange.
The other is a Four-point-matte or Eight-point matte to discard all the particles that still have color that cannot be deleted with the keyer without losing the orange.

If the area's overlap you can use Motion if you have it to make a more advanced matte then the 4 or 8 points matte and adjust that per frame over time if needed to discard colors of certain areas and keep the orange on other parts.

Hope that helps.

^no no no

it's a very simple effect... no mattes involved.

3-way color corrector, isolate the color you want with the eye dropper, click the checkbox for "invert", then drag saturation to 0.
