Section 2L: Adobe Photoshop Lesson: Replacing Color

In this lesson we will use Photoshop's Replace color tool to precisely adjust a specific color range. Like the Selective color tool, which can adjust a selected color throughout the entire image, Replace color can adjust the portion of the image we select. Though we could use the mask tool to select the portion of the image by drawing around the area we want to modify, we will have more control over the selection with Replace Color.

Usually you would make subtle changes to a particular color range, but in our example we will make big changes so to see more clearly. Ok lets get going…



Here is our original picture of a red Ferrari

Click Image menu - Adjust - Replace Color to bring up the Replace color window.
The aim here is to adjust the red color of our Ferrari. Move the window to one side allowing you to see the image.
Click the
Selection button (1)
Click the
color selector dropper (2)
Move the mouse pointer over to image and click on the color area you want to adjust (here I've clicked on a red section of the car).
The
black and white preview in the replace color window shows what is selected
The white area is "
Selected" and the black area is "non selected"
Click on the
Grow Select dropper (3) and click on another area of the color you wish to include in your selection (here I've selected a darker red on the car)
Using the
Fuzziness slider (4) we can select more or less of the image.
With the combination of the
Grow Select dropper (3) and the Fuzziness slider (4), we can select the color range we want to adjust. The preview above shows I have selected the red areas of the car and no background.
Ok that's the tricky part done, now to change the color!

 

Here using the Hue control (1) to the extreme, I now have a yellow Ferrari. The sample view (2) shows the color change.
Normally you would only want to make small changes to a color using the transform sliders. To make major changes like this you have to very critical in the selection process as non-selected parts wont change and we would end up with a polka dot Ferrari of red and yellow.
Click
OK to Apply.
Now that was easier than masking around all the red areas of the car!
I'll mail this to the Ferrari team and maybe next year we'll see a yellow Ferrari on the track! Or their attorneys on my back for defacing their car? :)
