I want to create paperhanging for my interior scene, and I want the Pattern on my Wallpaper to be Black and everything else to be its normal color, I tried but everything I can make is exactly the opposite what I want.
You need to create a mask (a black and white image) from the range of values you want to color in your image texture, explained in this answer.
In the nodes below I used a ColorRamp node to select the range of values (the highlights). You could set the interpolation of the color ramp node to Consent, but I left it at the default of Linear so that there is a smother transition between the original image and the new color.
The output from the color ramp is the mask. Plug that mask in to the Fac of the Mix node, the bottom socket is the color that all the highlights will be.
I did not have your exact texture, so the stops in your color ramp node may have to be in different spots to select the correct values.
