I noticed that many people are confused about the difference between color correction and color grading. This included myself when I first became more involved in film and film production. Once I understood the difference, I began to really pay attention to the color scheme of the movie and the color change when the film progressed.
To summarize the differences, color correction is the act of modifying the color of the material to make everything match. Color grading refers to the act of modifying a scene to have a certain hue to convey emotions, display changes, or somehow express certain special content.

As mentioned above, color correction is modifying the color of the material to match everything. The reason for this is due to many different factors. The most important thing is because the film was shot many days/night. Even a scene can be shot in multiple days. As you can imagine, each day will look a little different, and these changes will make the scene apparently not shot together rather than looking seamless. One day may be bright and sunny, and the next day may be cloudy. These two different types of days are very popular in movies. Color correction is applied during the editing process to modify the color of the scene to make it appear to be shot at the same time. This can be done by reducing the brightness of bright and sunny days, while also slightly brightening on cloudy days. A lot of measures must be taken, one of them is far apart, and try to meet in the middle. This can cause the scene to be too bright and "exploding." It is much easier to change from dark to bright multiple times from bright to dark.
The main reason for this is that the camera does not see too much detail in the darker scenes to make them brighter. A bright scene can look like a fairly easy night scene [called daytime night]. This is done a lot in the movie. I have seen such an example in American pies, when they drive through the town at night, they turn on the lights. It was shot during the day and they lowered the brightness to make it look like the night. The way you can notice this is sometimes to pay attention to the details in the entire framework. The real night scene usually has bright areas, with some dark areas outside the focus area. The night scene taken in one day will have the same detail and illumination for almost the entire scene.

Color grading is to modify the scene to have a specific hue. This can be done by conveying emotions or expressing multiple reasons for change. Our idea is to take the original material and add some color elements to the entire scene. An example is a scene with a blue hue to convey a clean look or a melancholy feel. An example of a movie appeared in Steven Soderbergh's film "Traffic." The film tells several storylines in parallel. Each storyline has a very unique tone.
One is blue and the other is orange. This makes it easy for us to notice the storyline we are experiencing. Of course, it may just be subconscious, but it's easier to follow. Many times, the group can be changed if it is expected to know the color to be used. For example, furniture and fixtures of certain colors will be placed in the scene, as the colors added to the scene in post-production [movie clips] look better. A good example of using color trends can be found in the links below. This shows an outline view of the movie Black Hawk Down. As you can see, as the film progresses, the color grading is slightly different. It is consistent for many scenes and then gradually changes to another color.

Finally, another recently used color grading is to make digital movies look more like they are shot on a movie. Lighting is an important part of this process, but color grading also has a huge impact on the appearance of the film, not the feeling of a digital home movie. If an independent filmmaker doesn't have enough money to buy a lot of light, they may be more color-graded to make their movies look more "normal" to someone.
I hope this article helps to understand the difference between color correction and color grading. I also hope that it will open your eyes to see the colors in the film, which may be a very powerful tool for conveying information.
