Does line colour matter?

[robs]

Hi, I've just been given a spool of braid that is hi-viz yellow, I am a bit concerned if this would spook fish or not. I was going to use it from the beach at Southend and possibly from the beach in Norfolk, two completely different conditions, one being a bit muddy and the other much clearer. Also I have some red coloured line and I was told that red disappears under water so would this be a good line for the clearer water in Norfolk? And advice would be gratefully received. Keep your rod bent, Robs.

had a similar conversation with a guy at the lake yesterday,
i have used bright yellow line for years both in my traces and hooklengths,

i really dont think it makes a difference in the sea,in freshwater i would not use it,

as for red disappearing underwater,i dont know about this,
why then do red maggots have such an appeal ?
if red things disappeared underwater surely the fish wouldnt be able to see them
