The setups will vary from camera model to camera model. You can do it using the multi matrix and a vector scope - having a set up chart will help. Basically you reduce the colour saturation until they're a tight bundle in the centre of the scope - it's a slow adjustment reducing each colour, so they don't cross over on the scope as you're pulling them down. Then adjust the red channel.

Then adjust the red channel.


Just be clear that we're talking about "red" in a matrix that can adjust hue and saturation, not the "Red channel" as in RGB. You can't adjust saturation with RGB levels. You'd just end up with a red-tinted image instead of a black and white image with a red subject in it.

Sometimes it can be tough to separate out red from the red component in fleshtones. You'll probably have to narrow the range or "width" quite a bit.

Yes, the red in the matrix.
