Color Filter

Another option is to try with Camera Raw filter. Here is what it looks like using Saturation only. I am using image from site provided above https://www.photoshopessentials.com/photo-effects/easy-selective-color-effect-with-photoshop/

With little bit of new masking feature you can remove red from lips and lights in the background.

Something like this?

Use Select > Color Range to pick your target color.

Then use that selection in a mask for a black and white adustment layer.
