Can the programmer's dice be distinguished by color?

First, by building a simple application, it will recognize the values of two 6-sided dice. Then use an ordinary pointer or open source project to adjust their distance from the camera, but their positions and directions will be random.

First, the program machine searches for a square outline with white or black as the main tone (the rest of the image, that is, the table/game surface, will have obviously different colors) for isolation, and then inputs the number of points.
