Answer:
this tutorial, we'll learn all about the Color Replacement Tool in Photoshop and how we can use it to easily change the color of objects in our photos!
Previously, we looked at the Background Eraser Tool and why it's one of the best tools in Photoshop for removing unwanted background areas of an image. You may be wondering why I mentioned it. I mean, what could a tool for erasing backgrounds possibly have to do with a tool for changing colors?
The answer is, a lot! The Background Eraser and the Color Replacement Tool both use the exact same methods for detecting pixels in the image that need to be changed. The only difference is that one of them erases pixels while the other simply changes their color. In fact, the tools are so similar that if you've already read through the Background Eraser tutorial and understand how it works, learning about the Color Replacement Tool will seem a lot like déjà vu.
Photoshop's Color Replacement Tool is not the most professional way to change colors in an image, and it won't always give you the results you need. But it usually works well for simple tasks and is such an easy tool to use that it's worth giving it a try before moving on to more advanced and time consuming methods.
