Need to change color. Hue/saturation isn't doing it for me

I have an image of some handmade paper.

How would i go about making the paper a darkish brown but still retain the texture. Hue/saturation doesn’t make it nearly dark enough. If i overlay a brown layer with an opacity then the texture is barely noticable.
