Color is differenct between LR/HR pairs

[YuqiangY]

Thanks for your nice work!
I noticed that the LR and HR might have different colors or brightness, the former might be a little darker than the latter.
So, have you ever found that? Looking forward to your reply.

The brightness and color of photos taken with cameras with different focal lengths are inherently different. The color and brightness correction has been done in the data set, otherwise the color and brightness deviation should be large
