Experimental Study on Color Identifiable Area Threshold Based on Visual Perception
Using color to encode data is a very common and important method in visual design. The rational use of color can improve the efficiency of information transmission. Therefore, we explored the effects of different levels of color on visual perception. From the perspective of minimum sensible difference and contrast sensitivity, the limit method is used to explore the minimum identifiable area of different levels of color, and the ability to recognize different levels of color is obtained. Based on the results, we made some suggestions: using the third and fourth level color coding key information, the seventh level coding the same level of information is not recommended. The results of this study can be used as a reference for interface color design to improve information readability.
