How to achieve the underlying layer result?

[mateuspollonio 11]

Hello, I have a doubt, how to give the same effect as the "underlying layer" of photoshop?
I know where the setting is in AF, but I don't know how to configure it to give the same effect.
For you to understand the context, I have a "recolor" setting, a background image and a character, each in its own layer.
I want to apply the "recolor" adjustment only to the character, but I want to apply the effect of the "underlying layer" of photoshop, as in the image I attached in this post.
Thank you

The values are entered in percentages in Photo rather than using the scale from 0 to 255 but otherwise  blending options work similarly (Photo curves just allowing more control). This would then be roughly the equivalent than shown in your screenshot from Photoshop "Blend if gray":

To limit the Recolor adjustment to the text layer, I'd nest it to this layer rather than trying to restrict the adjustment with blending options.
