As the question, I find the color of cross line (sprites)in the central of U-boat periscope is black in daylight. At night it changed into green , it's marked and clearly for shooting in the evening.

American subs do not have the same appliacnes. Who can help me how to change the periscope of USS into the German style? Just only in the cross line (sprites).

Thanks a lot for your kind help.
