As you can see Selective Color Panel image below, there are six main color channels, as well as channels for Whites (highlights), Neutrals (midtones) and Blacks (shadows).
This portrait image we are working with contains quite a bit of red, particularly on the subject’s face, so we are going to edit within the Reds channel first.
You will also notice there are two different modes of color processing: Relative and Absolute. Relative will display changes that are much more subtle than Absolute.
For basic color management, editing in Relative is sufficient.
As you can see below, the cyan slider in the Reds channel in Relative is set to +75, whereas cyan in Absolute only needs to be set to +20 to achieve the same effect as Relative at +75:
Within each color channel (Reds, Yellow, Greens, Cyan, Blues, Magenta, Whites, Neutrals and Blacks) you will have the ability to adjust Cyan, Magenta, Yellow and Black.
As you can see in the selective color panel image below, you can see which color each slider affects. Moving the slider to the right will increase the color, and moving the slider to the left will increase the opposite of that color. For example, when using the Magenta slider – if the slider is moved to the right, it will increase the magenta, but if the slider to the left, it will shift to the opposite of magenta (which is green).
For my image, I want to reduce the red cast, so in the Reds channel, I will move my cyan slider to the right, away from red, because I want to increase the cyan (and decrease the red).
After applying an adjustment, you can use the soft black brush to remove the adjustments in areas that you would like to remain untouched. In my example image, I want the subject’s face to show less red, but I still want to retain the warmth on the hardwood floors behind her, so I will remove the Selective Color adjustment from the floors:
Then, I will use the black brush, once again, to remove the effect from everything except her eyes and sweater:
Next, I want to add a touch of warmth to the subject’s face (the addition of cyan made her skin very cool) without making it red again, so, back in the Reds channel, I am going to boost the yellow slider:
I also removed the addition of yellow from everything except her face:
Once you are satisfied with your selective color adjustments, you may find it useful to group your layers
You can also reduce the opacity of the group in order to minimize the effect of the selective color adjustments:
Here is the before and after of all the adjustments that we just completed, with the adjustments grouped, and opacity reduced to 50%:
2. SELECTIVE CONTRAST ADJUSTMENTS
Since the Selective Color panel gives you the ability to edit Blacks, Whites and Neutrals,
Let’s look at how moving the black slider within the Blacks channel affects an image:
As you can see below, increasing (moving to the right) the black adds more contrast – this is due to the fact that this particular channel affects the shadows in your image (so by upping the black, you are increasing contrast).
The opposite is also true: if you move the slider to the left, the shadows will get lighter and gradually flatten out. This is one way to create hazy, soft blacks.
3. SELECTIVE EXPOSURE ADJUSTMENTS
For my image, I added a bit of cyan in the Whites channel to bring a cool tone to my highlights (this also helped me reduce any remaining red on the subject’s face).
I also reduced the black slider to brighten the highlights for the entire image:
In the Neturals channel, I did the same thing that I did in the Whites channel. Since the image is made up of mostly midtones (neutrals) this had a greater affect on my image, so I made a more subtle adjustment to the sliders than I did in the previous (Whites) channel:
Here is the before and after of the original image and the image after ALL of the steps described above:
CONCLUSION
We hope that this was a helpful introduction to the Selective Color panel in Photoshop! When it comes to editing color, everyone has their own style and idea of how they think their images should look, so be sure to use this panel in a way that suits your style.
