We will give you a detailed analysis of the optional color principles for users of photoshop software.
Analysis and sharing:
I believe many people have used this color palette command in PS, but few people really understand the principle and want to adjust their desired colors as they wish. Next I will analyze the available colors.
First, the optional color is the fading mode, the principle is the ink mixing color.
Four basic colors of ink: CMYK -- blue, magenta, yellow, and black.
Next let's take a look at the color map obtained by the three colors of green, foreign red, yellow, and respectively:
Three primary colors of blue, magenta, and yellow ink are the complementary colors of RGB colors. Below is the complementary relationship:
Red-cyan
Blue-red-yellow
Green-purple
The complementary relationship means you will not be there if you have me. You don't have me. So they are called complementary colors (forgive me for being a serious nonsense)
In the optional color palette, we change the color by changing the content of green, foreign red, yellow, and black.
Okay. Start now. You have these four kinds of ink in your hand.
What should I do when I want to bring up the red color? It is very simple. From the figure above, we can see that red is = Yellow + foreign red. That is to say, when I want to be red. Then I can get the red color by blending the red color with the yellow color.
Similarly: Blue = Cyan + magenta
Green = Foreign Red + yellow.
At this time, many people may not remember. Right? Look at the figure above. I must know. However, when this graph is not available. How can I remember it ?. Well, now we should look at the complementary relationship mentioned above.
Red and Blue are complementary colors, right? Are they irrelevant? If I do not have you, right? If the blue color is removed, does CMY contain foreign red and yellow. Is the mix of foreign red and yellow red?
That is to say, the foreign red, yellow, blue, three colors, and the other two colors are mixed, and the remaining colors are complementary.
You only need to remember: red, blue, yellow, green, and purple are the foreign red mentioned above.
Here are several examples to illustrate:
Example 1: How can I change the yellow color to blue?
First, these two are the basic colors in CMYK, and we only have these four colors of ink. (Emphasize again: in the optional color, the color is changed by changing the content of the four kinds of ink ).
Turn yellow into blue. I only need to select the yellow color, then the amount of yellow ink is reduced to zero, the amount of blue ink is adjusted to 100.
(Some may feel wrong. Why am I white? If there is no blue color, you can change the relative color options to absolute. I will analyze the relative and absolute differences later)
Example 2: Set the red color to blue. At this time, we should not look at the above figure, right?
The red color is the remaining two colors after the blue color, that is, yellow and purple.
Blue is the remaining two blue and purple after going yellow.
Then we need to turn the red color into blue, which is actually: Yellow + purple = (red) to: Green + purple (blue)
Do you just need to turn the yellow color into the blue color?
Tell me how to turn yellow to blue? If you do not know, please refer to the above.
Example 3: I want to change the grass in the figure below to green.
First, analyze the wave. The grass is yellow and red, right. Let's go first. Green Purple, (remove the purple. CMY is left with blue and yellow) that is to say, I need blue and yellow ink. As shown in the figure, the yellow ink already exists. Then I will add blue to it. Select the yellow color in the optional color. Add cyan
It seems to be a little blue. Is it very blue? There are still a lot of red ink in the grass in the figure. At this time, we need to remove the red. Let's go. Red. Oh, that is, adding a green color to the red color, then the red color will be deleted naturally. (Note that the red color below the original contact customer service offers has become black)
Here. Some people will still say that this is not what I want, and I think it is not enough. I suggest you copy several more adjustment layers.
I believe many of you have discovered this. You can use an optional color to color this huge weekly stamp. It's really troublesome. It may take a few seconds for me to adjust the color saturation.
Amount. Why did I overwrite myself after my hard work?
Example 4: adjust the following picture (this example is from the Baidu tutorial. Forgive the baby for being lazy)
In the figure, the Red Arrow refers to covering other places with masks and only wiping out the lips. Red lips in an optional color.
Final result:
Is there more artistic conception than before?
It can be found that the optional color is used to modify and adjust the color. However, it is convenient and quick to use the color palette without the color saturation.
Now let's talk about the relative and absolute differences. Relatively select a few percent of the ink in the current color to mix, so the front is relative. It is white when I reduce the yellow color to 100%. However, it remains unchanged when I move the cyan value to 100. It is because there is no blue ink in yellow.
So I moved the blue color to 100% without changing. It is definitely because I directly increase or decrease so much ink. It has nothing to do with the current color. So it's similar to my yellow ink. Then add the blue ink, so the figure becomes blue.
All right, the above information is the detailed optional color principle provided by the editor to the users of this software in photoshop, you can see the software users here. I believe that everyone is very clear now. I hope the parsing information above will help you.
