Most of the time, changing the color of an object in Photoshop is easy and straight forward. Most of the time, that is, when the object is a solid color. What happens though, when you are working with watercolor objects, or images that have blended colors?
While the options are a bit more limited, there are still ways to adjust and alter it to get the look that you are going for.
Step 1: As always, begin by selecting the object that you want to alter in the layers panel. Once selected, it will also be selected on your workspace.
Step 2: At the top of your screen, select "Image" and then "Adjustments".
Step 3: Now comes to fun part. Within the options listed for "Adjustments," you will be able to play around with the different options.
Brightness, Contrast, Levels, Curves, Exposure, Saturation, Black and White.
You can even adjust specific colors within the Black and White option! It really just takes a little patience and some creativity :)
Look at just a FEW of the outcomes that I got through these options!
Good luck and happy creating :)
