I always thought that if you got a particular brand line, colour would not matter as far as the breaking strain goes, but I have been thinking wrong.
Some very surprising results in the lower breaking strains.
Just goes to show, I tested some 7 lb line, small diam for the breaking strain, thought I might go the 4 lb, found it twice as thick and broke even higher than the 7 lb, wrong line on the spool. Finally got some 4 lb, nice and thin. You can never be quite sure.
