Applying RGB values to a Colour Mask. Is this doable?

Hello FCPX wizards.

I could use a little advice. I shot some garments on a white background. One of the garments was a pinkish/magenta color. It is fire engine red in the footage. Everything else is fine. Just the pink garment is off. I created a color mask and then found using the Colour Adjustments very crude. The client has offered a Pan tone number which I understand I should be able to translate into RGB numbers. Is there a way to apply specific RGB numbers to my color mask? How do I stop areas of similar color outside of my intended mask area (just that one garment) from being affected.

Thanks for any guidance.

A.T.

You can use the Keyer to chroma key the fire engine red color.

If it were me, I think I would try to color correct the clip to lighten the garment color, set the saturation to 0 (the luminosity of fire engine red is much darker than pink/magenta would be) and overlay the whole thing with a Solids > Custom generator (set to the color of your choice) with the Video > Compositing > Blend Mode set to Overlay.

I would place the Chroma Keyed clip over both the above.

There might be better ways...
