You can create different image layers, and use the Bucket Fill or Paintbrush tools in GIMP to change the color and hue of any item, element or area in an image.

Click the Layer tab at the top. You can find this button on the tab bar at the top of the app window (PC) or on the menu bar at the top of your screen (Mac).

Click New Layer on the Layer menu. This will allow you to create a new layer on your image. You can use this layer to make color manipulations on your image.

Select Transparency next to "Fill with. " In the "Create a New Layer" pop-up, make sure the "Transparency" option is selected as the layer fill at the bottom.

Click OK in the "Create a New Layer" pop-up. This will create a new, transparent layer on your image.

Click the Free Select (Lasso) tool in the toolkit. This button looks like a lasso icon in the toolkit section on the top-left. It will allow you to select an area in the picture.

Check the Feather edges option on the bottom-left. When you select the Free Select tool, you can enable this feature on the bottom-left of the app window.
- This will give softer edges to your selection.
- You can increase the Radius value under the "Feather edges" option for even softer edges.
-
Select the outline of the area you want to recolor. Use the Free Select (Lasso) tool with your mouse, and draw an outline around the area to recolor.
- Make sure the new, transparent layer is selected on the right-hand side, and not the original picture.
- When you finish the outline, you'll see dashed lines around your selection.
-
Click the "Bucket Fill" tool in the toolkit. This button looks like a paint bucket in the toolkit section in the upper-left corner.

Click the outlined area on the picture. This will fill the selected area with a solid color.
- Again, make sure the new, transparent layer is selected on the right-hand side; not the original image.
-
Click the Mode drop-down at the top of the Layers list. You can find a list of all your image layers on the right-hand side of the app window.
- By default, the layer mode should be set to "Normal."
-
Select Color in the Mode drop-down. This will change your transparent layer's mode to a "Color" layer, and change the color of the selected area in your original picture.
-
Select the Eraser tool in the toolkit. This button looks like a rectangle eraser icon in the toolkit section on the top-left.
-
Erase the extra color around the recolored area. You can use the Eraser tool to manually trim the edges, and remove the extra recolor around your selection.

Create a new, transparent layer. Follow the steps in the Part 2 above to create a new, transparent layer on top of your image with no fill.

Select the "Paintbrush" tool in the toolkit. This button looks like a paintbrush icon in the toolkit on the top-left of the app window.

Click the front color layer below the toolkit. On the left-hand side, click the front layer of the two color layers, and open the color selector.
-
Select the color you want to use on your paintbrush. You can select any color in the color selector pop-up or enter RGB/HTML values to pick an exact color.
-
Click the Mode drop-down at the top of the Layers. This drop-down menu is located at the top of all your image layers on the right-hand side, and should be set to "Normal" by default.
- Make sure the new, transparent layer you created for the paintbrush process is selected on the Layers list. Do not select the original picture here.
-
Select Hue in the Mode drop-down. This will allow you to change the color hue of the areas you paint with your paintbrush.
-
Paint on the picture to recolor anything. You can use your mouse to paint on the picture, and change the color hue of any part of the image.
- You should be painting on the transparent "Hue" layer, and not the original picture.
