如何辨別色彩失真
How to distinguish color distortion
對色彩失真的主要因素有了了解后，在實(shí)際生產(chǎn)過程中如何發(fā)現(xiàn)色彩失真才是關(guān)鍵。
After understanding the main factors of color distortion, how to find color distortion in the actual production process is the key.
1、首印象基準(zhǔn)法
1. First impression benchmark method
人的眼睛對色彩具有一定的適應(yīng)性。對于色彩輕微失真的圖像，反復(fù)觀察會減弱識別的能力。
Human eyes have certain adaptability to color. For images with slight color distortion, repeated observation will weaken the ability of recognition.
因此，在判斷是否存在色彩失真時，利用一眼的印象來排除人眼顏色視覺的局限性是發(fā)現(xiàn)色彩失真的重要方法。
Therefore, when judging whether there is color distortion, using one eye impression to eliminate the limitations of human color vision is an important method to find color distortion.
2、中性色基準(zhǔn)法
2. Neutral color reference method
生活中有許多中性色彩，如黑色、白色、灰色等，它們是繽紛世界中顏色的零點(diǎn)，我們可以作為辨別色彩失真的基點(diǎn)。
There are many neutral colors in life, such as black, white, gray and so on. They are the zero point of color in the colorful world. We can use them as the basic point to distinguish color distortion.
3、膚色基準(zhǔn)法
3. Skin color reference method
皮膚的顏色是人們熟悉的色彩，凡是人物圖像，尤其是以人物肖像為主的畫面，都可以根據(jù)皮膚的顏色作為辨別色彩失真的依據(jù)。
The color of skin is a familiar color. All character images, especially those based on portrait, can be used as the basis to distinguish color distortion according to the color of skin.
無論黃皮膚、白皮膚或黑皮膚，其膚色都有一個規(guī)律，那就是都是血色。即：黃中有紅、白里透紅或黑中泛紅，如果圖像中人物膚色偏黃就會給人產(chǎn)生病態(tài)的感覺。
Whether yellow skin, white skin or black skin, there is a law of skin color, that is, blood color. That is: red in yellow, red in white or red in black. If the skin color of the characters in the image is yellow, it will give people a morbid feeling.
在正常情況下，即使圖像中人物皮膚的顏色真的偏黃，在彩色校正時也要調(diào)整為血色，即黃中有紅。
Under normal circumstances, even if the skin color of the person in the image is really yellow, it should also be adjusted to blood color during color correction, that is, there is red in yellow.
