Adjust the image to metallic color

Quick answer：

To adjust an image to a metallic color effect, you can use image editing software like Adobe Photoshop or GIMP. The process typically involves adjusting the color balance, adding a metallic texture overlay, and using layer blending modes to achieve the desired metallic look. For Photoshop, you might use a combination of the 'Color Balance' and 'Hue/Saturation' tools, along with blending layers using 'Overlay' or 'Hard Light' modes.
