I have a question about recoloring in Photoshop. Any help is appreciated.

I have been running into problems when recoloring textures for models in that I know of no way to recolor an image towards a specific color without using a solid color fill. It's important, as I'm trying to make colors match between different objects, and solid color fills destroy lightness gradation.

This is one of the textures I am working on, with a sample color pasted into the upper left side(the small pattern in a brighter gold color). I'd like to learn a method of taking a sample color from from the lighter gold part and then using that exact color as a reference to change the color of the darker gold part to match it using Photoshop, ideally while preserving the black and the changes in lightness from black>gold in the original.

Thus far, I haven't been able to figure out an exact method, and so have been judging it by eye using the hue adjustment layer(although I have had some success with the color balance adjustment layer function).

The best method I have found so far is recoloring the portion I want to change to black and white and then inputting the exact number of the color I want to bias towards into the color balance layer, but it's still not exact(only gets close to reproducing the color it started from, for example).

Sorry for the wall of text.
