Here is a sample cheat sheet you can save to help make your gold textures. Save it and open it in Photoshop. Use the eye dropper to sample the colors. Use a dark and a light to make your texture.
1. Make a new blank canvas of size of your choice. I'm using 800x800px. Change the background and foreground colors to #b27467 and #e0b8ac for a rose gold foil texture effect.
2. Go to Filter- Render- Clouds. You can do this as many times as you like to change up the clouds effect.
3. Filter-Noise- Add Noise. Add noise between 6 and 10. Make sure uniform and monochromatic are selected in the add noise box.
4. Filter- Filter Gallery.
5. Distort- Glass. Set distortion to 20 smoothness between 3 and 5. You can play with the scaling and invert to your liking then click ok and save your gold foil texture.
