I haven’t lived that long, but one of the lessons I’ve learned is that nothing is 100% satisfactory.
Starting from your self-image in the mirror to a hamburger with tomato (disappear from the Earth, tomato!), once you start to be disgruntled about something, there is no end to it.
Photos are no exception. In almost every picture, there is room for improvement.
Or you may find that the whole picture needs to be improved. Okay, okay. Let’s go step by step.
First is how to change colors.

 

Shall we try changing the color of the wall in this picture?
But before starting, you can see that the only color in this picture is”¦ blue. Of course, there is black and white but they don’t qualify as color as they only indicate brightness and darkness in this picture. This makes everything simple.

 

Go to Image > Adjustment > Hue/Saturation. Or you may want to memorize Ctr+U for hot key.

 

you see the control panel? Let’s take a look at it starting from the top.

 

Adjust the Hue value to change the blue into another color.
Hue function replaces the existing color value with another color.
As mentioned above, black and white remain intact as they are not colors.

 

And the next is to adjust saturation. As you move to higher ““ value, the color becomes more turbid. If you move to the + side, on the other than, the closer it becomes to the primary color.

 

And the last one is lightness. Higher + value brightens up the whole picture. Lower the value”¦ and you know what happens.

 

Good enough. Then, how do we change a particular color in a multi-color picture?

 

Let’s take a look at this photo.
The red signboard that reads “MUSEUM” really stands out. Definitely a good subject to follow the effect of color change.

 

Go to Image > Adjustment and select Replace Color.

 

You will see that a new control board has been created.
Using the spoid icon, click on the area where you want to change the color, like I did in the area marked in blue circle.
As seen in the red square, the area that you selected will appear white against a black background. Fuzziness is used to change the range of the selected color. As you can see here, if you adjust fuzziness to maximum, other areas including the signboard marked in white come under the range. But I only want to change the signboard and nothing else. So let’s adjust the number to around 130.

 

Below is a function called “˜Replacement’. Looks familiar? It’s the same control board as the Hue/Saturation control board we just saw. The functions are the same. Let’s try clicking on the color in Result box. A color control box will pop up next to it. You can pick and choose whatever color you want, which will be instantly reflected on the signboard.

 

And you can do this with anything in the photo. If you move the cursor and place it on the original photo, the cursor will change to a spoid frame. Let’s click on the statue standing in front of the building.

 

The signboard is now the same color as the statue.

 

You can try the same procedure for many different purposes. For example, transforming a person you dislike into a Smurf or Shrek.”¦
I hope you do not enrage someone, though.
