Are the photos of the Republic of China in color?

At that time, the camera pixel was not high, and it was imported from abroad. You can look at some people's photos of the Republic of China and find that they are black and white, which makes sense. Because the camera at that time couldn't take colorful photos, it can't be compared now. Just look at a few photos, Zhang and Wu. Take a closer look. Research, now you know. Thank you. Please adopt
