Before studying, it is necessary for us to get to know the picture below. There's no more talking about it. Rgb,cmy. The figures in this picture have been changed by me, mainly for the convenience of everyone to understand. is to match the hue adjustment. The value here corresponds to the value of hue. -180--0--180. Corresponds to the angle of this picture. This picture can be seen as a 60 degree difference between each two colors.

First, do a test, create a new layer, CTRL+J copy layer, the general copy of the layer will be more secure, the best habit. Draws a rectangular box of three colors. Fills in red (r=255 g=0 b=0), Green (r=0 g=255 b=0), Blue (r=0 g=0), respectively.

Bring up the Hue/Saturation panel (shortcut key Ctrl+u). Set the hue to 60 to get the image below. You can see the original red into the yellow, the original green into the cyan. The blue turns to magenta. Now look at the picture of step one, which is equivalent to r--y,g--c,b--m.

In the same step, bring up the Hue/Saturation panel (shortcut key Ctrl+u). Set the hue to 180 to get the image below. Can see the original red into the cyan, the original green into the magenta. The original blue turned yellow. Now look at the picture of step one, which is equivalent to r--c,g--m,b--y.

Here, you can find that the change in the value of the hue and step in the picture in the value of the change is synchronized, hue of 60, then r--y,g--c,b--m. The equivalent color is changed clockwise 60 degrees. The value of Hue is 180, then r--c,g--m,b--y. The equivalent color is changed clockwise 180 degrees. (If the value of the hue is a negative number, it is equivalent to counterclockwise change)!

The values here are set by me to make it easier to understand. It is important to understand the patterns of change in vision. Here is an example to illustrate.

For example, open a picture, found that the people in the picture of the skin is yellow, we want to add a bit of blood color of the human face. Even a person's complexion is slightly red.

Turn on the hue/Saturation panel and adjust the hue value to-14, even if the color of the picture in step one rotates 14 degrees counterclockwise, making the yellow y biased towards the red R. is not very simple.

For example, if you want to turn the blue sky into Twilight, you can turn blue to yellow.

Create a new hue/saturation adjustment panel, adjust the hue according to the rules of step one, and to make the blue yellow, you can adjust the value of hue to 180 or 180. (This is only to illustrate the principle, the real map should be adjusted according to the actual situation) after the appearance of the following figure.

Then use the black brush to erase the change in the hue of the weed, then set the opacity to 75%. You can get the picture below.

Summary: Remember step one of the picture, want to change the color of a picture on the basis of the hue of the positive and negative values and pictures of the corresponding diagram of the clockwise adjustment of hue, and then with the help of masks, opacity, curves and other tools to modify.
