This is a tutorial on changing specific colors in an image using the color range tool in Photoshop.
You can use this tutorial to easily change regions of color in an image to different colors. This can be very useful if you want to make a part of an image fit into the color scheme of the background or even just changing the color of someones dress or a clothing item.
Photoshop Version: CS2 (Can apply to Earlier versions up to Photoshop 7)
The first step here is to go to the menu [Select->Color Range].
Then click on the area of color in the image that you want to change. Here we are clicking on a red part of the women’s dress.
The end goal for this tutorial is to change the color of her dress.
You can use the plus and minus eyedropper buttons to add more regions of color to the selection. Here we are just using one sampling of red. Adjust the fuzziness. (The amount of similar colors to the one you clicked to add to the range. If you go higher it will select any kind of red, if you go lower, it will only select a ceartain amount of reds similar the the area of her dress that you clicked)
Click ok to see the selected area of the image. As you can see here, we selected her dress but her lips are close to the same color so they were selected as well. The next step shows you how to remove those areas that you want to leave alone.
Click on the “Edit in quick mask mode button on the toolbox. This will bring you into the “Quick Mask” mode which will allow you to edit the selection by using the brush tool.
All of the areas that are pink are the areas that are not selected. Select the brush tool and make sure your foreground color is black. Paint out the area around her lips and head. This will remove the selection from those areas.
Once you have done this, click the “edit in standard mode” in the toolbox. This will return you to standard mode where you can see the dancing ants around what is selected. You will notice that the area that you painted out is no longer selected.
Now you can do whatever you want with her dress because you now have it selected. Here I show you how to change her dress color from red to purple. Go to the Menu [Image->Adjustments->Hue/Saturation] and set the settings shown here. You can also experiment with the sliders to see what colors you can get.
Here is the finished dress showing the color has been changed.
