The Selective
color tool is convenient for correcting specific colors in an image.
Although associated with the name "selective," this tool is used for performing color compensation of a specific color,
not a selection. When using Adjustment layer to perform color compensation, there is also a method of partial compensation
of an image using a Layer mask. However, making the outline in this method is difficult, and there are many operation steps.
In contrast, although the method using Selective color introduced here has few steps, it can
achieve partial compensation with a clear outline.
However, it is effective only in images in which
the selected color and the surrounding portion are clearly different. Please use this tool
properly or combine two methods according to the characteristics of the image. |
|
|
Open an image that has a specific
color distinct from the surrounding area. As mentioned before, this adjustment is best used on colors
that are distinct from the surrounding area. In this example, you will attempt to change the color
of the scooter sitting on the boardwalk. |
 |
|
From the [IMAGE] menu, select
[Adjustments], then [Selective color]. In the dialog box, pick the specific color range you want,
such as RedsS or MagentasS. Monochromatic colorsS such as whites, grays, or blacks can also be
selected. To change the scooter color, select Reds.S |
|
Since RedsS was chosen for adjustment,
four sliders (Cyan,S Magenta,S Yellow,S and BlackS) appear in the dialog box. Moving one of the
sliders to the left decreases the amount of that color whereas moving it to the right increases the
color. In other words, moving the slider towards the Plus side increases the color and moving it
towards the Minus side increases that colors compliment. |

 |
| Move the SYellowS slider
towards Minus,S increasing blue. Also move the SBlackS slider towards SMinus.S The result
is a pink scooter. |
|
| (A) |
Moving the SCyanS slider towards SMinusS increases red, and moving it
towards SPlusS increases cyan. |
| (B) |
Moving the SMagentaS slider towards SMinusS increases green, and moving
it towards SPlusS increases magenta. |
| (C) |
Moving the SYellowS slider towards SMinusS increases blue, and moving
it towards SPlusS increases yellow. |
| (D) |
Moving the SBlackS slider towards SMinusS brightens the image; moving
it towards SPlusS darkens the image. |
|
|
|
|
 |
First, move the SYellowS slider towards SMinusS and
the red scooter becomes pink. |
 |
|
Next move the SBlackS slider towards SMinusS and
the pink becomes lighter. Now you have a light-pink scooter. |
 |
 |
| At the bottom of
the dialog box you can choose from two methods, "Relative" and "Absolute." In the absolute
method, each color slider can be set to a value from K100 to +100. In the relative method, the
slider represents a percentage (%) change relative to the value of the present color. |
|
That is, in the "absolute" method,
moving a slider +20% (noting that the original color ingredient was 50% red) makes 70%
red. In the relative method, 10% is added (20% of the 50% red), and the value becomes
60% red. |
