How to Change Object Colors in GIMP

Changing object colors in GIMP is a versatile technique that can be used for various design purposes, from simple color corrections to more creative effects. In this tutorial, we'll show you three different methods to change object colors in GIMP, helping you achieve the exact look you want.

Step 1: Select the Object

1. First, open your image in GIMP.
2. Use the Path Tool (or any other selection tool) to create a precise selection around the object you want to change the color of. For this example, we’ll use the Path Tool to select a sofa.
3. Once you’ve made the selection, press Enter to create the selection from the path. If you see the path outline and want to remove it, simply select another tool.

Step 2: Duplicate the Layer

1. Before applying any color changes, duplicate the layer with the selected object three times. This will allow you to use different methods on separate layers for comparison.
2. Name the duplicated layers as Hue, Colorize, and Layers to keep them organized.

Method 1: Hue and Saturation

1. Select the Hue layer and go to Colors > Hue-Saturation.
2. In the Hue-Saturation window, you can adjust the color (Hue), brightness (Lightness), and color intensity (Saturation).
3. You can also target specific colors within the selection by clicking on individual color channels like Red, Green, or Blue.
4. Once you’re satisfied with the color change, press OK to apply the effect.

Method 2: Colorize

1. Hide the Hue layer and select the Colorize layer.
2. Go to Colors > Colorize to open the Colorize window.
3. Adjust the Hue, Saturation, and Lightness sliders to achieve the desired color change.
   • A useful feature of the Colorize method is the ability to pick colors from the image or manually choose a color by clicking on the color box.
4. After making your adjustments, press OK to apply the color change.

Method 3: Layer Modes

1. Hide the Colorize layer and select the Layers layer.
2. Create a new transparent layer above the Layers layer by clicking on the New Layer icon and choosing Transparency.
3. Fill the selection on the new layer with your desired color. You can do this by selecting the color, then dragging it into the selection area.
4. Change the layer mode to LCH Color or HSL Color to blend the new color with the object beneath it.
5. Adjust the layer opacity or apply gradients to achieve different effects. This method is particularly useful when you want to apply color gradients or simulate materials like gold or silver.
