In addition, the method of judgment of the bias is introduced: determine a reference color.
The method selected here is here, one is to select highlight, and the other is to select the middle.
Because there are art foundations, you must know that the color of these two parts is relatively single:
The high light portion is composed of light source;
The intermediate surface is mainly the object of the object.
Other such as bright and dark interfaces, dark faces, projections, etc. are composed of two or more colors, which are more complicated, and is not recommended here.
The closer color of these two faces and the known color, the smaller the bias, the more serious it is. I chose the high-gloss part, (the head is more white, a relatively bright place) is known to be white as a white as a reference color, with a pipette tool to test, found that the RGB value is at 253, 253, 253 to 255, 255, 255. Embody fluctuations. That is, this part is basically white. fulfill our requirement. Figure
