When using the iPad version of Infuse, I found that the subtitle color was not right, as if it had been washed with water. When playing the same video on an iPhone, this problem also exists. So I compared another player on the same iPad platform with commonly used players on the PC platform, and found that this problem does not exist.
I have excerpted a portion of the original video and attached the complete ASS subtitle file. I will list the time when the color error occurred
